| Summary: Development files for expat, an XML parser toolkit | |
Expat is an XML parser library written in C. It is a stream-oriented parser in which an application registers handlers for things the parser might find in the XML document (like start tags). This package contains the development headers for the library found in libexpat.

* Thu Mar 26 2026 David Anes <david.anes@suse.com>
- version update to 2.7.5 (bsc#1259711, bsc#1259729, bsc#1259726)
* CVE-2026-32776 -- Fix NULL function pointer dereference for
empty external parameter entities; it takes use of both
functions XML_ExternalEntityParserCreate and
XML_SetParamEntityParsing for an application to be
vulnerable.
* CVE-2026-32777 -- Protect from XML_TOK_INSTANCE_START
infinite loop in function entityValueProcessor; it takes
use of both functions XML_ExternalEntityParserCreate and
XML_SetParamEntityParsing for an application to be
vulnerable.
* CVE-2026-32778 -- Fix NULL dereference in function setContext
on retry after an earlier ouf-of-memory condition; it takes
use of function XML_ParserCreateNS or XML_ParserCreate_MM
for an application to be vulnerable.
* See full changelog here:
https://github.com/libexpat/libexpat/blob/R_2_7_5/expat/Changes
* Tue Feb 03 2026 Petr Gajdos <pgajdos@suse.com>
- version update to 2.7.4
* CVE-2026-24515 -- Function XML_ExternalEntityParserCreate
failed to copy the encoding handler data passed to
XML_SetUnknownEncodingHandler from the parent to the new
subparser. This can cause a NULL dereference (CWE-476) from
external entities that declare use of an unknown encoding.
The expected impact is denial of service. It takes use of
both functions XML_ExternalEntityParserCreate and
XML_SetUnknownEncodingHandler for an application to be
vulnerable.
* CVE-2026-25210 -- Add missing check for integer overflow
related to buffer size determination in function doContent
* lib: Fix missing undoing of group size expansion in doProlog
failure cases
* xmlwf: Fix a memory leak
* WASI: Fix format specifiers for 32bit WASI SDK
- fixes [bsc#1257144] and [bsc#1257496]
* Sat Sep 27 2025 Christoph G <foss@grueninger.de>

architectures (e.g. sparc32); fixes up on the fix to
CVE-2025-59375 (of Expat 2.7.2)
* Fix a class of false positives where input should have been
rejected with error XML_ERROR_ASYNC_ENTITY; regression from
CVE-2024-8176 (of Expat 2.7.0)
* Prove and regression-proof absence of integer overflow
from function expat_realloc

and XML_GetErrorColumnNumber
* Mon Sep 22 2025 pgajdos@suse.com

* xmlwf: Mention supported environment variables in
- -help output
* see Changes for details

* Fri Mar 14 2025 pgajdos@suse.com
- version update to 2.7.0 (CVE-2024-8176 [bsc#1239618])
* Security fixes:
[#893] #973 CVE-2024-8176 -- Fix crash from chaining a large number
of entities caused by stack overflow by resolving use of
recursion, for all three uses of entities:
- general entities in character data ("<e>&g1;</e>")
- general entities in attribute values ("<e k1='&g1;'/>")
- parameter entities ("%p1;")
Known impact is (reliable and easy) denial of service:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:H/RL:O/RC:C
(Base Score: 7.5, Temporal Score: 7.2)
Please note that a layer of compression around XML can
significantly reduce the minimum attack payload size.

* Thu Sep 26 2024 pgajdos@suse.com
- updated keyring [https://build.suse.de/request/show/345282]
- modified sources
% expat.keyring
* Thu Sep 05 2024 David Anes <david.anes@suse.com>
- Update to 2.6.3:
* Security fixes:
- CVE-2024-45490, bsc#1229930 -- Calling function XML_ParseBuffer with
len < 0 without noticing and then calling XML_GetBuffer
will have XML_ParseBuffer fail to recognize the problem
and XML_GetBuffer corrupt memory.
With the fix, XML_ParseBuffer now complains with error
XML_ERROR_INVALID_ARGUMENT just like sibling XML_Parse
has been doing since Expat 2.2.1, and now documented.
Impact is denial of service to potentially artitrary code
execution.
- CVE-2024-45491, bsc#1229931 -- Internal function dtdCopy can have an
integer overflow for nDefaultAtts on 32-bit platforms
(where UINT_MAX equals SIZE_MAX).
Impact is denial of service to potentially artitrary code
execution.
- CVE-2024-45492, bsc#1229932 -- Internal function nextScaffoldPart can
have an integer overflow for m_groupSize on 32-bit
platforms (where UINT_MAX equals SIZE_MAX).
Impact is denial of service to potentially artitrary code
execution.
* Other changes:

to 10:3:9 (libexpat*.so.1.9.3); see https://verbump.de/
for what these numbers do
* Wed Mar 13 2024 Andreas Stieger <andreas.stieger@gmx.de>
- update to 2.6.2:
* CVE-2024-28757 -- Prevent billion laughs attacks with isolated
use of external parsers (boo#1221289)
* Reject direct parameter entity recursion and avoid the related
undefined behavior
* Fri Mar 01 2024 Andreas Stieger <andreas.stieger@gmx.de>
- update to 2.6.1:
* Expose billion laughs API with XML_DTD defined and XML_GE
undefined, regression from 2.6.0
* Make tests independent of CPU speed, and thus more robust
- drop libxml2-fix-xmlwf.1-handling.patch, upstream
* Tue Feb 20 2024 David Anes <david.anes@suse.com>
- Fix handling of xmlwf.1 to avoid workarounds in specfile:
* Added libxml2-fix-xmlwf.1-handling.patch
- Call buildconf.sh to avoid (future) issues with expat_config.h.in

- Update keyring automatically from keyserver during OBS service run.
- Explicitly use --without-docbook (before it was implicit).
- Include missing files for documentation and examples.
- Add manpage for xmlwf, which is now available in the released tarball.
- Clean the spec file a bit.
- Update to 2.6.0:
* Security fixes:
- CVE-2023-52425 (boo#1219559, bsc#1221563)
- - Fix quadratic runtime issues with big tokens
that can cause denial of service, in partial where
dealing with compressed XML input. Applications
that parsed a document in one go -- a single call to
functions XML_Parse or XML_ParseBuffer -- were not affected.
The smaller the chunks/buffers you use for parsing
previously, the bigger the problem prior to the fix.
Backporters should be careful to no omit parts of
pull request #789 and to include earlier pull request #771,
in order to not break the fix.
- CVE-2023-52426 (boo#1219561)
- - Fix billion laughs attacks for users
compiling *without* XML_DTD defined (which is not common).
Users with XML_DTD defined have been protected since
Expat >=2.4.0 (and that was CVE-2013-0340 back then).
* Bug fixes:
- Fix parse-size-dependent "invalid token" error for
external entities that start with a byte order mark
- Fix NULL pointer dereference in setContext via
XML_ExternalEntityParserCreate for compilation with
XML_DTD undefined
- Protect against closing entities out of order
* Other changes:
- Improve support for arc4random/arc4random_buf
- Improve buffer growth in XML_GetBuffer and XML_Parse
- xmlwf: Support --help and --version
- xmlwf: Support custom buffer size for XML_GetBuffer and read
- xmlwf: Improve language and URL clickability in help output

- Autotools: Make installation of shipped man page doc/xmlwf.1
independent of docbook2man availability

section "Cflags.private" in order to fix compilation
against static libexpat using pkg-config on Windows

a build with -DEXPAT_BUILD_TESTS=ON
- docs: Document the importance of isFinal + adjust tests
accordingly
- docs: Improve use of "NULL" and "null"
