Description

Security update for expat This update for expat fixes the following issues: Version update to 2.7.1: * Bug fixes: * Restore event pointer behavior from Expat 2.6.4 (that the fix to CVE-2024-8176 changed in 2.7.0); affected API functions are: - XML_GetCurrentByteCount - XML_GetCurrentByteIndex - XML_GetCurrentColumnNumber - XML_GetCurrentLineNumber - XML_GetInputContext * Other changes: #976 #977 Autotools: Integrate files "fuzz/xml_lpm_fuzzer.{cpp,proto}" with Automake that were missing from 2.7.0 release tarballs #983 #984 Fix printf format specifiers for 32bit Emscripten #992 docs: Promote OpenSSF Best Practices self-certification #978 tests/benchmark: Resolve mistaken double close #986 Address compiler warnings #990 #993 Version info bumped from 11:1:10 (libexpat*.so.1.10.1) to 11:2:10 (libexpat*.so.1.10.2); see https://verbump.de/ for what these numbers do Infrastructure: #982 CI: Start running Perl XML::Parser integration tests #987 CI: Enforce Clang Static Analyzer clean code #991 CI: Re-enable warning clang-analyzer-valist.Uninitialized for clang-tidy #981 CI: Cover compilation with musl #983 #984 CI: Cover compilation with 32bit Emscripten #976 #977 CI: Protect against fuzzer files missing from future release archives Version update to 2.7.0 (CVE-2024-8176 [bsc#1239618]) * Security fixes: * 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. * Other changes: * Document changes since the previous release * Version info bumped from 11:0:10 (libexpat*.so.1.10.0) to 11:1:10 (libexpat*.so.1.10.1); see https://verbump.de/ for what these numbers do Version update to 2.6.4: * Security fixes: [bsc#1232601][bsc#1232579] * CVE-2024-50602 -- Fix crash within function XML_ResumeParser from a NULL pointer dereference by disallowing function XML_StopParser to (stop or) suspend an unstarted parser. A new error code XML_ERROR_NOT_STARTED was introduced to properly communicate this situation. // CWE-476 CWE-754 * Other changes: * Version info bumped from 10:3:9 (libexpat*.so.1.9.3) to 11:0:10 (libexpat*.so.1.10.0); see https://verbump.de/ for what these numbers do 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: - Version info bumped from 10:2:9 (libexpat*.so.1.9.2) to 10:3:9 (libexpat*.so.1.9.3); see https://verbump.de/ for what these numbers do Update to 2.6.2: * CVE-2024-28757 -- Prevent billion laughs attacks with isolated use of external parsers (bsc#1221289) * Reject direct parameter entity recursion and avoid the related undefined behavior 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 Update to 2.6.0: * Security fixes: - CVE-2023-52425 (bsc#1219559) 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 (bsc#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 - examples: Add new example "element_declarations.c" - Be stricter about macro XML_CONTEXT_BYTES at build time - Make inclusion to expat_config.h consistent - Autotools: configure.ac: Support --disable-maintainer-mode - Autotools: Sync CMake templates with CMake 3.26 - Autotools: Make installation of shipped man page doc/xmlwf.1 independent of docbook2man availability - Autotools|CMake: Add missing -DXML_STATIC to pkg-config file section "Cflags.private" in order to fix compilation against static libexpat using pkg-config on Windows - Autotools|CMake: Require a C99 compiler (a de-facto requirement already since Expat 2.2.2 of 2017) - Autotools|CMake: Fix PACKAGE_BUGREPORT variable - Autotools|CMake: Make test suite require a C++11 compiler - CMake: Require CMake >=3.5.0 - CMake: Lowercase off_t and size_t to help a bug in Meson - CMake: Sort xmlwf sources alphabetically - CMake|Windows: Fix generation of DLL file version info - CMake: Build tests/benchmark/benchmark.c as well for a build with -DEXPAT_BUILD_TESTS=ON - docs: Document the importance of isFinal + adjust tests accordingly - docs: Improve use of "NULL" and "null" - docs: Be specific about version of XML (XML 1.0r4) and version of C (C99); (XML 1.0r5 will need a sponsor.) - docs: reference.html: Promote function XML_ParseBuffer more - docs: reference.html: Add HTML anchors to XML_* macros - docs: reference.html: Upgrade to OK.css 1.2.0 - docs: Fix typos - docs|CI: Use HTTPS URLs instead of HTTP at various places - Address compiler warnings - Address clang-tidy warnings - Version info bumped from 9:10:8 (libexpat*.so.1.8.10) to 10:0:9 (libexpat*.so.1.9.0); see https://verbump.de/ for what these numbers do
