* Thu Oct 09 2025 Martin Hauke <mardnh@gmx.de>
- Update to version 2.2.0
No change in API in this release.
* Added functions dwarf_lvn_name_direct() dwarf_lvn_name()
dwarf_lvn_table_entry() to allow complete reading of
DWARF6 DW_AT_language_version attributes.
* Fixed issues reading corrupted (fuzzed) Apple Mach-o
object files: now the code immediately returns an error
instead of seeming stuck.
* Fixed issues building with gcc option -std=c99 and the like.
* Corrected a bug reading line table data that used forms
similar to DWARF5 DW_FORM_strx.
* Fri Sep 19 2025 Martin Hauke <mardnh@gmx.de>
- Update to version 2.1.0
* Removed heuristic checs for decompression reasonableness as
they failed on some real object files.
* Corrected handling and reporting of the DWARF6 attributes
DW_AT_language_name and DW_AT_language_version.
* An object with DWARF and GNU debuglink data and nothing else
is now correctly accepted and reported.
- Update to version 2.0.0
* Fixed a longstanding bug in configure.ac which began to cause
builds to fail with recent autoconf.
* Updated the error report (for zlib, zstd) when decompression
exceeds a heuristic limit.
- Update to version 0.12
* Improved the code in dwarfdump checking for valid address
ranges (-k options).
* Added the capability of using mmap instead of malloc in
reading section data and functions allowing reporting on
section malloc/mmap.
* Now detects duplicated attributes and generates an error and
provides a way to suppress the detection (for cases where one
needs to analyze an object that was created with a broken
compiler).
- Add patch:
* libdwarf-both.patch
- Use meson instead of autotools
- Build dwarfgen
- Run testsuite
- Use %ldconfig_scriptlets macro
* Sun Mar 30 2025 Dirk Müller <dmueller@suse.com>
- update to 0.11.1:
* Updated document date to today.
* Each file has 1 to 3 trivial casts added and all
involve things whose known range ensures
the change is ok (boolean, address-size, and other known
things)..
* Removing trailing whitespace and fixing a couple
indent mistakes.
* Now checks and reports on all DIE references, meaning
the DWARF reference class.
* Now uses a macro for 0x%08llx clarifying printf on
Dwarf_Unsigned.
* Also removes an accidental trailing space in printed
output.
* In one place in code added yesterday an explicit dealloc
of a Dwarf_Error was omitted. Found by the usual
export NLIZE=y export SUPPRESSDEALLOCTREE=y
regressiontest.
* The code refactoed to print attributes:
DW_AT_specification:
DW_AT_abstract_origin:
DW_AT_type:
is now in place and this commit
deletes the lines extracted to the new source file.
* build: fix arguments order in calloc calls (#258)
* Initial addition of ossfuzz 70753 and ossfuzz 70763
* Sun Aug 18 2024 Dirk Müller <dmueller@suse.com>
- update to 0.11.0:
* Identifies git fix id now for ossfuzz 70721
DW202407-010
* Correcting use-after-free with a specific corrupted
DWARF section.
* This simplfies getting correct cooked
addresses for entries from .debug_ranges
* The new code about .debug_ranges had
small leaks when the library was told
not to record or clean-up most memory allocations.
Shown by -fsanitize.
* Fixed a mistake in examplev, .debug_ranges
* Added new argument to print_ranges_list_to_extra()
so it can print both raw and cooked values.
* Now calulates the cooked value of .debug_ranges
and prints both raw and cooked values.
* New date, some Dwarf_Ranges doc has been updated
in libdwarf.
* Added clarifying comment paragraphs about Dwarf_Ranges
* Final on the rnglists ossfuzz issues so far.
* ossfuzz 70246 DW202407-002 fixed.
* Removing esb_append_printf() which is the last use of *sprintf()
* ossfuzz 70244 fixed DW202407-001
* Removing esb_append_printf() as it is no
longer necessary.
* Added blank line after d= semantic version
* Fixed trailing whitespace and indents.
* Refine the information on rnglists base with
* cc_rnglists_base_via_at (similar to loclists)
* Added cc_loclists_base_via_at and
* Due to the addition of dwarf_get_locdesc_entry_e()
we revise the version for the next release to be
* Issue #247, github libdwarf-code.
* Fix indents and eliminate trailing whitespace.
* Corrected the gitfixid as there was
a use-after-free in new-today code, now fixed.
* Fixing a nasty double free that was caused a few
minutes ago.
* New oss fuzz 69639 and 69641 are fixed.
Here identfied as DW202406-001 and DW202406-002
* Remove debug printf (was #if 0 ... #endif)
Fixed DW202406-001 ossfuzz 69639
and
DW202406-002 ossfuzz 69641
* Implemented spelling change ld_kind to ld_lkind
* In dwarf_formref() we correct the reading
of DW_FORM_loclistx and DW_FORM_rnglistx
to read a uleb. Been wrong since 2022 at least..
Another spot reading these had it right all along.
* Renamed ll_kind to ll_lkind as it names a DW_LKIND value
* Renamed ld_kind to ld_lkind as it names a DW_LKIND value
* Revises the dwarfdump reporting of debug_loclists to
clarify the dwarf 5 debug_loclists structure content.
* The --print-raw-loclists option is more useful now.
* Revises the dwarfdump reporting of debug_rnglists to
clarify the dwarf 5 debug_rnglists structure content.
* The --print-raw-rnglists option is more useful now.
* In certain error cases the revised rnglists code
was failing to dwarf_dealloc_error() where
* Updated the output format of --print-raw-loclists
to be more useful and to essentially match the rnglists
version.
* Separated out part of loclists data structs to
be a better match with dwarf_rnglists.h
* Corrected calculations related to rnglists array of
offsets (were calling entries address size when they are offset
size).
* Removed some lines related to merging skeleton and split,
they were wrong. debug_rnglists and debug_rnglists.dwo
* Initialize the three new fields in Dwarf_Debug_s
used for DWARF5 GNU extension .debug_addr printing.
* Renaming DW_DLE_PE_SECTION_SIZE_ERROR
to DW_DLE_PE_SECTION_SIZE_HEURISTIC_FAIL
so any failure of the three such tests are
clearly reported. Should never happen.
* A heuristic sanity check on section VirtualSize
was too concervative at s00MB, a PE object file had a
section over 200MB in size.
* Adding release xz name
* Wed May 29 2024 Dominique Leuenberger <dimstar@opensuse.org>
- Update to version 0.9.2:
+ Fixed four vulnerabilities that could crash the library
(segmentation violation etc) reading specific corruptions to
DWARF.
DW202402-001, DW202402-002,DW202402-003, and DW202403-001.
Now the library returns an error code for those. Corrected a
dwarf.h misspelling of DW_CFA_hi_user.
* Tue Jan 30 2024 Dirk Müller <dmueller@suse.com>
- update to 0.9.1:
* "--disable-decompression" tells the build to compile
libdwarf and dwarfdump with no reference to the zlib or
zstd libraries.
* Latest DW_LANG names now present.
- build with zstd support
* Thu Dec 28 2023 Dirk Müller <dmueller@suse.com>
- update to 0.9.0:
* Added support for reading Apple MacOS universal binaries.
* Added callers access to certain fields from object files
(for all three supported object formats), and
* added the --print-machine-arch option to dwarfdump to show the
fields.
* Three functions were added to the API, see the Changes section
of the latest documentation or in libdwarf.pdf in the release.
No functions were deleted or had their meaning changed.
* Vulnerabilities found by fuzzing were fixed.
* See https://www.prevanders.net/dwarfbug.html for vulnerability
details.
* Sat Nov 18 2023 Dirk Müller <dmueller@suse.com>
- update to 0.8.0:
* The release fixes many vulnerabilities from corrupt DWARF
and/or corrupt Elf. Two new functions are added for DWARF Frame
access to get the correct sign of an argument (the pre-existing
functions remain in place and working avoiding any need for
recompilation or relinking of user code).
* Mon May 29 2023 Dirk Müller <dmueller@suse.com>
- update to 0.7.0:
* The release fixes more than 50 vulnerabilities from corrupt
DWARF and/or corrupt Elf.
* Elf section counts can exceed 16 bits (on linux see man 5 elf)
so some function prototype members of struct
Dwarf_Obj_Access_Methods_a_s changed. Specifically,
om_get_section_info() om_load_section(), and om_relocate_a_section()
now pass section indexes as Dwarf_Unsigned instead of Dwarf_Half.
* Two functions have been removed from libdwarf.h and the library:
dwarf_dnames_abbrev_by_code() and dwarf_dnames_abbrev_form_by_index().
* dwarf_dnames_abbrev_by_code() is slow and pointless. Use either
dwarf_dnames_name() or dwarf_dnames_abbrevtable() instead,
depending on what you want to accomplish.
* dwarf_dnames_abbrev_form_by_index() is not needed, was difficult
to call due to argument list requirements, and never worked.
* Mon Feb 27 2023 Dirk Müller <dmueller@suse.com>
- update to 0.6.0:
Fixes for Denial Of Service (possible libdwarf crash):
* The dealloc required for dwarf_offset_list() was incorrect,
possibly leading to a crash.
* The function prototype for dwarf_dietype_offset() changed so
it can work correctly on DWARF4 objects.
* A memory leak from dwarf_load_loclists() has been fixed.
* The function dwarf_get_pubtypes() changed, Dwarf_Type no longer
exists, correcting a library design mistake made in 1993.
The function applied to DWARF3 and DWARF4 objects.
* The set of functions using Dwarf_Type are gone, use Dwarf_Global
instead. An object with DW_FORM_strx3 (DWARF5) could result in
the library either crashing or returning an inappropriate error.
DW_FORM_strx3 is now handled
