0BSD
* Thu Apr 03 2025 Antonio Teixeira <antonio.teixeira@suse.com>
- Update to 5.8.1:
* Multithreaded .xz decoder (lzma_stream_decoder_mt()):
- Fix a bug that could at least result in a crash with
invalid input. (bsc#1240414, CVE-2025-31115)
- Fix a performance bug: Only one thread was used if the whole
input file was provided at once to lzma_code(), the output
buffer was big enough, timeout was disabled, and LZMA_FINISH
was used. There are no bug reports about this, thus it's
possible that no real-world application was affected.
* Avoid <stdalign.h> even with C11/C17 compilers. This fixes the
build with Oracle Developer Studio 12.6 on Solaris 10 when the
compiler is in C11 mode (the header doesn't exist).
* Autotools: Restore compatibility with GNU make versions older
than 4.0 by creating the package using GNU gettext 0.23.1
infrastructure instead of 0.24.
* Update Croatian translation.
- 5.8.0 changelog:
* liblzma on 32/64-bit x86: When possible, use SSE2 intrinsics
instead of memcpy() in the LZMA/LZMA2 decoder. In typical cases,
this may reduce decompression time by 0-5 %. However, when built
against musl libc, over 15 % time reduction was observed with
highly compressed files.
* CMake: Make the feature test macros match the Autotools-based
build on NetBSD, Darwin, and mingw-w64.
* Update the Croatian, Italian, Portuguese, and Romanian
translations.
* Update the German, Italian, Korean, Romanian, Serbian, and
Ukrainian man page translations.
- Summary of changes in the 5.7.x development releases:
* Mark the following LZMA Utils script aliases as deprecated:
lzcmp, lzdiff, lzless, lzmore, lzgrep, lzegrep, and lzfgrep.
* liblzma:
- Improve LZMA/LZMA2 encoder speed on 64-bit PowerPC (both
endiannesses) and those 64-bit RISC-V processors that
support fast unaligned access.
- Add low-level APIs for RISC-V, ARM64, and x86 BCJ filters
to lzma/bcj.h. These are primarily for erofs-utils.
- x86/x86-64/E2K CLMUL CRC code was rewritten.
- Use the CRC32 instructions on LoongArch.
* xz:
- Synchronize the output file and its directory using fsync()
before deleting the input file. No syncing is done when xz
isn't going to delete the input file.
- Add --no-sync to disable the sync-before-delete behavior.
- Make --single-stream imply --keep.
* xz, xzdec, lzmainfo: When printing messages, replace
non-printable characters with question marks.
* xz and xzdec on Linux: Support Landlock ABI versions 5 and 6.
* CMake: Revise the configuration variables and some of their
options, and document them in the file INSTALL. CMake support
is no longer experimental. (It was already not experimental
when building for native Windows.)
* Add build-aux/license-check.sh.
* Sun Feb 02 2025 Andreas Stieger <andreas.stieger@gmx.de>
- update to 5.6.4:
* liblzma: Fix LZMA/LZMA2 encoder on big endian ARM64.
* xz: Fix --filters= and --filters1= ... --filters9= options
parsing. They require an argument, thus "xz --filters lzma2"
should work in addition to "xz --filters=lzma2".
* Updates to documentation, translations, build system files
- package license files in all packages
* Mon Oct 07 2024 Antonio Teixeira <antonio.teixeira@suse.com>
- Update to 5.6.3:
* liblzma:
- Fix x86-64 inline assembly compatibility with GNU Binutils
older than 2.27.
- Fix the build with GCC 4.2 on OpenBSD/sparc64.
* xzdec: Display an error instead of failing silently if the
unsupported option -M is specified.
* lzmainfo: Fix integer overflows when rounding the dictionary and
uncompressed sizes to the nearest mebibyte.
* Autotools-based build:
- Fix feature checks with link-time optimization (-flto).
- Solaris: Fix a compatibility issue in version.sh. It matters
if one wants to regenerate configure by running autoconf.
* CMake:
- Use paths relative to ${prefix} in liblzma.pc when possible.
This is done only with CMake >= 3.20.
- Prefer a C11 compiler over a C99 compiler but accept both.
- Link Threads::Threads against liblzma using PRIVATE so that
- pthread and such flags won't unnecessarily get included in
the usage requirements of shared liblzma. That is,
target_link_libraries(foo PRIVATE liblzma::liblzma) no
longer adds -pthread if using POSIX threads and linking
against shared liblzma. The threading flags are still added
if linking against static liblzma.
* Updated translations: Catalan, Chinese (simplified), and
Brazilian Portuguese.
* Thu May 30 2024 Paolo Stivanin <info@paolostivanin.com>
- Update to 5.6.2:
* Remove the backdoor (CVE-2024-3094).
* Not changed: Memory sanitizer (MSAN) has a false positive
in the CRC CLMUL code which also makes OSS Fuzz unhappy.
Valgrind is smarter and doesn't complain.
A revision to the CLMUL code is coming anyway and this issue
will be cleaned up as part of it. It won't be backported to
5.6.x or 5.4.x because the old code isn't wrong. There is
no reason to risk introducing regressions in old branches
just to silence a false positive.
* liblzma:
- lzma_index_decoder() and lzma_index_buffer_decode(): Fix
a missing output pointer initialization (*i = NULL) if the
functions are called with invalid arguments. The API docs
say that such an initialization is always done. In practice
this matters very little because the problem can only occur
if the calling application has a bug and these functions
return LZMA_PROG_ERROR.
- lzma_str_to_filters(): Fix a missing output pointer
initialization (*error_pos = 0). This is very similar
to the fix above.
- Fix C standard conformance with function pointer types.
- Remove GNU indirect function (IFUNC) support. This is *NOT*
done for security reasons even though the backdoor relied on
this code. The performance benefits of IFUNC are too tiny in
this project to make the extra complexity worth it.
- FreeBSD on ARM64: Add error checking to CRC32 instruction
support detection.
- Fix building with NVIDIA HPC SDK.
* xz:
- Fix a C standard conformance issue in --block-list parsing
(arithmetic on a null pointer).
- Fix a warning from GNU groff when processing the man page:
"warning: cannot select font 'CW'"
* xzdec: Add support for Linux Landlock ABI version 4. xz already
had the v3-to-v4 change but it had been forgotten from xzdec.
* Fri Apr 12 2024 Dirk Müller <dmueller@suse.com>
- revert the switch to tar_scm which dropped the signature
validation
- switch back to tarballs because the upstream tarballs are not
gone
- reinstanciate keyring from Lasse
- go back to the last release signed by Lasse (5.4.2)
- revert multibuild, drop service and rpmlintrc
- use real_ver for the Source, move everything else back to
%version like before the hectic XZ downgrade
- remove payload setting, we are using zstd now
* Thu Apr 04 2024 Dan Čermák <dcermak@suse.com>
- Switch to using tar_scm for fetching the sources as the upstream
tarballs on github are gone
- introduce _multibuild to allow building the translations outside
of Ring0 and everything else in Ring0
- add rpmlintrc to silence harmless warnings
* Thu Mar 28 2024 Dirk Müller <dmueller@suse.com>
- restore a bigger version number so that update works
* Mon Jan 29 2024 Danilo Spinella <danilo.spinella@suse.com>
- Build static library on SLE
* Sun Jan 28 2024 Dirk Müller <dmueller@suse.com>
- update to 5.4.6:
* Fixed a bug involving internal function pointers in liblzma
not being initialized to NULL. The bug can only be
triggered if lzma_filters_update() is called on a LZMA1
encoder, so it does not affect xz or any application known
to us that uses liblzma.
* Fixed a regression introduced in 5.4.2 that caused
encoding in the raw format to unnecessarily fail if --suffix
was not used. For instance, the following command no longer
reports that --suffix must be used:
echo foo | xz --format=raw --lzma2 | wc -c
* Fixed an issue on MinGW-w64 builds that prevented
reading from or writing to non-terminal character devices
like NUL.
* Added a new test.
* Tue Nov 07 2023 Andrea Manzini <andrea.manzini@suse.com>
- Update to version 5.4.5:
* liblzma:
- Fixed an assertion failure that could be triggered by a large
unpadded_size argument. It was verified that there was no
other bug than the assertion failure.
- Fixed a bug that prevented building with Windows Vista
threading when __attribute__((__constructor__)) is not
supported.
* xz now properly handles special files such as "con" or "nul" on
Windows. Before this fix, the following wrote "foo" to the
console and deleted the input file "con_xz":
echo foo | xz > con_xz
xz --suffix=_xz --decompress con_xz
* Small fixes and improvements to the tests.
* Updated translations: Chinese (simplified) and Esperanto.
* Wed Aug 16 2023 Dominique Leuenberger <dimstar@opensuse.org>
- xznew: Remove bashsism.
- build: pass CONFIG_SHELL=/bin/sh to configure: the posix tools
are setting the current SHELL as the shebang, which is overkill:
any posix compliant shell, aka /bin/sh, is sufficient.
* Thu Aug 03 2023 Paolo Stivanin <info@paolostivanin.com>
- Update to version 5.4.4:
* liblzma and xzdec can now build against WASI SDK when threading
support is disabled. xz and tests don't build yet.
* documentation update
* translations update
* Fri May 05 2023 Andreas Stieger <andreas.stieger@gmx.de>
- Update to version 5.4.3:
* Build system fixes
* Translation updates: Croatian
- update signing key
* Thu Apr 06 2023 Frederic Crozat <fcrozat@suse.com>
- Update license tag, there is GPL-3.0-or-later code too.
* Mon Mar 20 2023 Martin Pluskal <mpluskal@suse.com>
- Update to version 5.4.2:
* All fixes from 5.2.11 that were not included in 5.4.1.
* If xz is built with support for the Capsicum sandbox but running
in an environment that doesn't support Capsicum, xz now runs
normally without sandboxing instead of exiting with an error.
* liblzma:
- Documentation was updated to improve the style, consistency,
and completeness of the liblzma API headers.
- The Doxygen-generated HTML documentation for the liblzma API
header files is now included in the source release and is
installed as part of "make install". All JavaScript is
removed to simplify license compliance and to reduce the
install size.
- Fixed a minor bug in lzma_str_from_filters() that produced
too many filters in the output string instead of reporting
an error if the input array had more than four filters. This
bug did not affect xz.
* Build systems:
- autogen.sh now invokes the doxygen tool via the new wrapper
script doxygen/update-doxygen, unless the command line option
- -no-doxygen is used.
- Added microlzma_encoder.c and microlzma_decoder.c to the
VS project files for Windows and to the CMake build. These
should have been included in 5.3.2alpha.
* Tests:
- Added a test to the CMake build that was forgotten in the
previous release.
- Added and refactored a few tests.
* Translations:
- Updated the Brazilian Portuguese translation.
- Added Brazilian Portuguese man page translation.
* Wed Mar 08 2023 Martin Pluskal <mpluskal@suse.com>
- Build AVX2 enabled hwcaps library for x86_64-v3
* Sat Jan 21 2023 Dirk Müller <dmueller@suse.com>
- update to 5.4.1:
* liblzma:
- Fixed the return value of lzma_microlzma_encoder() if the
LZMA options lc/lp/pb are invalid. Invalid lc/lp/pb options
made the function return LZMA_STREAM_END without encoding
anything instead of returning LZMA_OPTIONS_ERROR.
* Tests:
- Fixed test script compatibility with ancient /bin/sh
versions. Now the five test_compress_* tests should
no longer fail on Solaris 10.
- Added and refactored a few tests.
* Translations:
- Updated the Catalan and Esperanto translations.
- Added Korean and Ukrainian man page translations.
* Fri Dec 30 2022 Dirk Müller <dmueller@suse.com>
- update to 5.4.0:
This bumps the minor version of liblzma because new features were
added. The API and ABI are still backward compatible with liblzma
5.2.x and 5.0.x.
Summary of new features added in the 5.3.x development releases:
* liblzma:
- Added threaded .xz decompressor lzma_stream_decoder_mt().
It can use multiple threads with .xz files that have multiple
Blocks with size information in Block Headers. The threaded
encoder in xz has always created such files.
Single-threaded encoder cannot store the size information in
Block Headers even if one used LZMA_FULL_FLUSH to create
multiple Blocks, so this threaded decoder cannot use multiple
threads with such files.
If there are multiple Streams (concatenated .xz files), one
Stream will be decompressed completely before starting the
next Stream.
- A new decoder flag LZMA_FAIL_FAST was added. It makes the
threaded decompressor report errors soon instead of first
flushing all pending data before the error location.
- New Filter IDs:
* LZMA_FILTER_ARM64 is for ARM64 binaries.
* LZMA_FILTER_LZMA1EXT is for raw LZMA1 streams that don't
necessarily use the end marker.
- Added lzma_str_to_filters(), lzma_str_from_filters(), and
lzma_str_list_filters() to convert a preset or a filter chain
string to a lzma_filter[] and vice versa. These should make
it easier to write applications that allow users to specify
custom compression options.
- Added lzma_filters_free() which can be convenient for freeing
the filter options in a filter chain (an array of lzma_filter
structures).
- lzma_file_info_decoder() to makes it a little easier to get
the Index field from .xz files. This helps in getting the
uncompressed file size but an easy-to-use random access
API is still missing which has existed in XZ for Java for
a long time.
- Added lzma_microlzma_encoder() and lzma_microlzma_decoder().
It is used by erofs-utils and may be used by others too.
The MicroLZMA format is a raw LZMA stream (without end marker)
whose first byte (always 0x00) has been replaced with
bitwise-negation of the LZMA properties (lc/lp/pb). It was
created for use in EROFS but may be used in other contexts
as well where it is important to avoid wasting bytes for
stream headers or footers. The format is also supported by
XZ Embedded (the XZ Embedded version in Linux got MicroLZMA
support in Linux 5.16).
The MicroLZMA encoder API in liblzma can compress into a
fixed-sized output buffer so that as much data is compressed
as can be fit into the buffer while still creating a valid
MicroLZMA stream. This is needed for EROFS.
- Added lzma_lzip_decoder() to decompress the .lz (lzip) file
format version 0 and the original unextended version 1 files.
Also lzma_auto_decoder() supports .lz files.
- lzma_filters_update() can now be used with the multi-threaded
encoder (lzma_stream_encoder_mt()) to change the filter chain
after LZMA_FULL_BARRIER or LZMA_FULL_FLUSH.
- In lzma_options_lzma, allow nice_len = 2 and 3 with the match
finders that require at least 3 or 4. Now it is internally
rounded up if needed.
- CLMUL-based CRC64 on x86-64 and E2K with runtime processor
detection. On 32-bit x86 it currently isn't available unless
- -disable-assembler is used which can make the non-CLMUL
CRC64 slower; this might be fixed in the future.
- Building with --disable-threads --enable-small
is now thread-safe if the compiler supports
__attribute__((__constructor__)).
* xz:
- Using -T0 (--threads=0) will now use multi-threaded encoder
even on a single-core system. This is to ensure that output
from the same xz binary is identical on both single-core and
multi-core systems.
- --threads=+1 or -T+1 is now a way to put xz into
multi-threaded mode while using only one worker thread.
The + is ignored if the number is not 1.
- A default soft memory usage limit is now used for compression
when -T0 is used and no explicit limit has been specified.
This soft limit is used to restrict the number of threads
but if the limit is exceeded with even one thread then xz
will continue with one thread using the multi-threaded
encoder and this limit is ignored. If the number of threads
is specified manually then no default limit will be used;
this affects only -T0.
This change helps on systems that have very many cores and
using all of them for xz makes no sense. Previously xz -T0
could run out of memory on such systems because it attempted
to reserve memory for too many threads.
This also helps with 32-bit builds which don't have a large
amount of address space that would be required for many
threads. The default soft limit for -T0 is at most 1400 MiB
on all 32-bit platforms.
- Previously a low value in --memlimit-compress wouldn't cause
xz to switch from multi-threaded mode to single-threaded mode
if the limit cannot otherwise be met; xz failed instead. Now
xz can switch to single-threaded mode and then, if needed,
scale down the LZMA2 dictionary size too just like it already
did when it was started in single-threaded mode.
- The option --no-adjust no longer prevents xz from scaling down
the number of threads as that doesn't affect the compressed
output (only performance). Now --no-adjust only prevents
adjustments that affect compressed output, that is, with
- -no-adjust xz won't switch from multi-threaded mode to
single-threaded mode and won't scale down the LZMA2
dictionary size.
- Added a new option --memlimit-mt-decompress=LIMIT. This is
used to limit the number of decompressor threads (possibly
falling back to single-threaded mode) but it will never make
xz refuse to decompress a file. This has a system-specific
default value because without any limit xz could end up
allocating memory for the whole compressed input file, the
whole uncompressed output file, multiple thread-specific
decompressor instances and so on. Basically xz could
attempt to use an insane amount of memory even with fairly
common files. The system-specific default value is currently
the same as the one used for compression with -T0.
The new option works together with the existing option
- -memlimit-decompress=LIMIT. The old option sets a hard limit
that must not be exceeded (xz will refuse to decompress)
while the new option only restricts the number of threads.
If the limit set with --memlimit-mt-decompress is greater
than the limit set with --memlimit-compress, then the latter
value is used also for --memlimit-mt-decompress.
- Added new information to the output of xz --info-memory and
new fields to the output of xz --robot --info-memory.
- In --lzma2=nice=NUMBER allow 2 and 3 with all match finders
now that liblzma handles it.
- Don't mention endianness for ARM and ARM-Thumb filters in
- -long-help. The filters only work for little endian
instruction encoding but modern ARM processors using
big endian data access still use little endian
instruction encoding. So the help text was misleading.
In contrast, the PowerPC filter is only for big endian
32/64-bit PowerPC code. Little endian PowerPC would need
a separate filter.
- Added decompression support for the .lz (lzip) file format
version 0 and the original unextended version 1. It is
autodetected by default. See also the option --format on
the xz man page.
- Sandboxing enabled by default:
* Capsicum (FreeBSD)
* pledge(2) (OpenBSD)
* Scripts now support the .lz format using xz.
* A few new tests were added.
* The liblzma-specific tests are now supported in CMake-based
builds too ("make test").
* Sat Dec 17 2022 Dirk Müller <dmueller@suse.com>
- update to 5.2.10:
* xz: Don't modify argv[] when parsing the --memlimit* and
- -block-list command line options. This fixes confusing
arguments in process listing (like "ps auxf").
* GNU/Linux only: Use __has_attribute(__symver__) to detect if
that attribute is supported. This fixes build on Mandriva where
Clang is patched to define __GNUC__ to 11 by default (instead
of 4 as used by Clang upstream).
* liblzma:
- Fixed an infinite loop in LZMA encoder initialization
if dict_size >= 2 GiB.
- Fixed two cases of invalid free() that can happen if
a tiny allocation fails in encoder re-initialization
or in lzma_filters_update(). These bugs had some
similarities with the bug fixed in 5.2.7.
- Fixed lzma_block_encoder() not allowing the use of
LZMA_SYNC_FLUSH with lzma_code() even though it was
documented to be supported. The sync-flush code in
the Block encoder was already used internally via
lzma_stream_encoder(), so this was just a missing flag
in the lzma_block_encoder() API function.
- GNU/Linux only: Don't put symbol versions into static
liblzma as it breaks things in some cases (and even if
it didn't break anything, symbol versions in static
libraries are useless anyway). The downside of the fix
is that if the configure options --with-pic or --without-pic
are used then it's not possible to build both shared and
static liblzma at the same time on GNU/Linux anymore;
with those options --disable-static or --disable-shared
must be used too.
- drop unused xz-devel-static which is no longer supported when using
- -with-pic (which is needed for shared libs)
* Thu Dec 01 2022 Jan Engelhardt <jengelh@inai.de>
- Rename xz-static-devel -> xz-devel-static to follow the general
naming used in openSUSE.
* Fri Nov 18 2022 Danilo Spinella <danilo.spinella@suse.com>
- Update to 5.2.8:
* xz:
- If xz cannot remove an input file when it should, this
is now treated as a warning (exit status 2) instead of
an error (exit status 1). This matches GNU gzip and it
is more logical as at that point the output file has
already been successfully closed.
- Fix handling of .xz files with an unsupported check type.
Previously such printed a warning message but then xz
behaved as if an error had occurred (didn't decompress,
exit status 1). Now a warning is printed, decompression
is done anyway, and exit status is 2. This used to work
slightly before 5.0.0. In practice this bug matters only
if xz has been built with some check types disabled. As
instructed in PACKAGERS, such builds should be done in
special situations only.
- Fix "xz -dc --single-stream tests/files/good-0-empty.xz"
which failed with "Internal error (bug)". That is,
- -single-stream was broken if the first .xz stream in
the input file didn't contain any uncompressed data.
- Fix displaying file sizes in the progress indicator when
working in passthru mode and there are multiple input files.
Just like "gzip -cdf", "xz -cdf" works like "cat" when the
input file isn't a supported compressed file format. In
this case the file size counters weren't reset between
files so with multiple input files the progress indicator
displayed an incorrect (too large) value.
* liblzma:
- API docs in lzma/container.h:
* Update the list of decoder flags in the decoder
function docs.
* Explain LZMA_CONCATENATED behavior with .lzma files
in lzma_auto_decoder() docs.
- OpenBSD: Use HW_NCPUONLINE to detect the number of
available hardware threads in lzma_physmem().
- Fix use of wrong macro to detect x86 SSE2 support.
__SSE2_MATH__ was used with GCC/Clang but the correct
one is __SSE2__. The first one means that SSE2 is used
for floating point math which is irrelevant here.
The affected SSE2 code isn't used on x86-64 so this affects
only 32-bit x86 builds that use -msse2 without -mfpmath=sse
(there is no runtime detection for SSE2). It improves LZMA
compression speed (not decompression).
- Fix the build with Intel C compiler 2021 (ICC, not ICX)
on Linux. It defines __GNUC__ to 10 but doesn't support
the __symver__ attribute introduced in GCC 10.
* Scripts: Ignore warnings from xz by using --quiet --no-warn.
This is needed if the input .xz files use an unsupported
check type.
* Translations:
- Updated Croatian and Turkish translations.
- One new translations wasn't included because it needed
technical fixes. It will be in upcoming 5.4.0. No new
translations will be added to the 5.2.x branch anymore.
- Renamed the French man page translation file from
fr_FR.po to fr.po and thus also its install directory
(like /usr/share/man/fr_FR -> .../fr).
- Man page translations for upcoming 5.4.0 are now handled
in the Translation Project.
* Update doc/faq.txt a little so it's less out-of-date.
* Tue Oct 04 2022 Callum Farmer <gmbr3@opensuse.org>
- Move localised man pages to lang subpackage
* Fri Sep 30 2022 C J <c.j@tuta.io>
- update to 5.2.7:
* liblzma:
- Add API doc note about the .xz decoder LZMA_MEMLIMIT_ERROR bug.
- Add dest and src NULL checks to lzma_index_cat.
The documentation states LZMA_PROG_ERROR can be returned from
lzma_index_cat. Previously, lzma_index_cat could not return
LZMA_PROG_ERROR. Now, the validation is similar to
lzma_index_append, which does a NULL check on the index
parameter.
- Fix copying of check type statistics in lzma_index_cat().
The check type of the last Stream in dest was never copied to
dest->checks (the code tried to copy it but it was done too late).
This meant that the value returned by lzma_index_checks() would
only include the check type of the last Stream when multiple
lzma_indexes had been concatenated.
In xz --list this meant that the summary would only list the
check type of the last Stream, so in this sense this was only
a visual bug. However, it's possible that some applications
use this information for purposes other than merely showing
it to the users in an informational message. I'm not aware of
such applications though and it's quite possible that such
applications don't exist.
Regular streamed decompression in xz or any other application
doesn't use lzma_index_cat() and so this bug cannot affect them.
- Stream decoder: Fix restarting after LZMA_MEMLIMIT_ERROR.
If lzma_code() returns LZMA_MEMLIMIT_ERROR it is now possible
to use lzma_memlimit_set() to increase the limit and continue
decoding. This was supposed to work from the beginning but
there was a bug. With other decoders (.lzma or threaded .xz)
this already worked correctly.
- lzma_filters_copy: Keep dest[] unmodified if an error occurs.
lzma_stream_encoder() and lzma_stream_encoder_mt() always assumed
this. Before this patch, failing lzma_filters_copy() could result
in free(invalid_pointer) or invalid memory reads in stream_encoder.c
or stream_encoder_mt.c.
To trigger this, allocating memory for a filter options structure
has to fail. These are tiny allocations so in practice they very
rarely fail.
Certain badness in the filter chain array could also make
lzma_filters_copy() fail but both stream_encoder.c and
stream_encoder_mt.c validate the filter chain before
trying to copy it, so the crash cannot occur this way.
- lzma_index_append: Add missing integer overflow check.
The documentation in src/liblzma/api/lzma/index.h suggests that
both the unpadded (compressed) size and the uncompressed size
are checked for overflow, but only the unpadded size was checked.
The uncompressed check is done first since that is more likely to
occur than the unpadded or index field size overflows.
- Vaccinate against an ill patch from RHEL/CentOS 7.
* xzgrep:
- Fix compatibility with old shells.
Turns out that some old shells don't like apostrophes (') inside
command substitutions. The problem was introduced by commits
69d1b3fc29677af8ade8dc15dba83f0589cb63d6 (2022-03-29),
bd7b290f3fe4faeceb7d3497ed9bf2e6ed5e7dc5 (2022-07-18), and
a648978b20495b7aa4a8b029c5a810b5ad9d08ff (2022-07-19).
5.2.6 is the only stable release that included
this problem.

- update to 5.2.6 (CVE-2022-1271, bsc#1198062):
* xz:
- The --keep option now accepts symlinks, hardlinks, and
setuid, setgid, and sticky files.
- When copying metadata from the source file to the destination
file, don't try to set the group (GID) if it is already set
correctly. This avoids a failure on OpenBSD (and possibly on
a few other OSes) where files may get created so that their
group doesn't belong to the user, and fchown(2) can fail even
if it needs to do nothing.
- Cap --memlimit-compress to 2000 MiB instead of 4020 MiB on
MIPS32 because on MIPS32 userspace processes are limited
to 2 GiB of address space.
* liblzma:
- Fixed a missing error-check in the threaded encoder. If a
small memory allocation fails, a .xz file with an invalid
Index field would be created. Decompressing such a file would
produce the correct output but result in an error at the end.
Thus this is a "mild" data corruption bug. Note that while
a failed memory allocation can trigger the bug, it cannot
cause invalid memory access.
- The decoder for .lzma files now supports files that have
uncompressed size stored in the header and still use the
end of payload marker (end of stream marker) at the end
of the LZMA stream. Such files are rare but, according to
the documentation in LZMA SDK, they are valid.
doc/lzma-file-format.txt was updated too.
- Improved 32-bit x86 assembly files:
* Support Intel Control-flow Enforcement Technology (CET)
* Use non-executable stack on FreeBSD.
* xzgrep:
- Fixed arbitrary command injection via a malicious filename
(CVE-2022-1271, ZDI-CAN-16587). A standalone patch for
this was released to the public on 2022-04-07. A slight
robustness improvement has been made since then and, if
using GNU or *BSD grep, a new faster method is now used
that doesn't use the old sed-based construct at all. This
also fixes bad output with GNU grep >= 3.5 (2020-09-27)
when xzgrepping binary files.
- Fixed detection of corrupt .bz2 files.
- Improved error handling to fix exit status in some situations
and to fix handling of signals: in some situations a signal
didn't make xzgrep exit when it clearly should have. It's
possible that the signal handling still isn't quite perfect
but hopefully it's good enough.
- Documented exit statuses on the man page.
- xzegrep and xzfgrep now use "grep -E" and "grep -F" instead
of the deprecated egrep and fgrep commands.
- Fixed parsing of the options -E, -F, -G, -P, and -X. The
problem occurred when multiple options were specied in
a single argument, for example,
echo foo | xzgrep -Fe foo
treated foo as a filename because -Fe wasn't correctly
split into -F -e.
- Added zstd support.
* xzdiff/xzcmp:
- Fixed wrong exit status. Exit status could be 2 when the
correct value is 1.
- Documented on the man page that exit status of 2 is used
for decompression errors.
- Added zstd support.
* xzless:
- Fix less(1) version detection. It failed if the version number
from "less -V" contained a dot.
* Tue Apr 12 2022 Marcus Meissner <meissner@suse.com>
- use https urls.
