### Summary #### 2.6.0 ``` Release 2.6.0 Tue February 6 2024 Security fixes: #789 #814 CVE-2023-52425 -- 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. #777 CVE-2023-52426 -- 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: #753 Fix parse-size-dependent "invalid token" error for external entities that start with a byte order mark #780 Fix NULL pointer dereference in setContext via XML_ExternalEntityParserCreate for compilation with XML_DTD undefined #812 #813 Protect against closing entities out of order Other changes: #723 Improve support for arc4random/arc4random_buf #771 #788 Improve buffer growth in XML_GetBuffer and XML_Parse #761 #770 xmlwf: Support --help and --version #759 #770 xmlwf: Support custom buffer size for XML_GetBuffer and read #744 xmlwf: Improve language and URL clickability in help output #673 examples: Add new example "element_declarations.c" #764 Be stricter about macro XML_CONTEXT_BYTES at build time #765 Make inclusion to expat_config.h consistent #726 #727 Autotools: configure.ac: Support --disable-maintainer-mode #678 #705 .. #706 #733 #792 Autotools: Sync CMake templates with CMake 3.26 #795 Autotools: Make installation of shipped man page doc/xmlwf.1 independent of docbook2man availability #815 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 #724 #751 Autotools|CMake: Require a C99 compiler (a de-facto requirement already since Expat 2.2.2 of 2017) #793 Autotools|CMake: Fix PACKAGE_BUGREPORT variable #750 #786 Autotools|CMake: Make test suite require a C++11 compiler #749 CMake: Require CMake >=3.5.0 #672 CMake: Lowercase off_t and size_t to help a bug in Meson #746 CMake: Sort xmlwf sources alphabetically #785 CMake|Windows: Fix generation of DLL file version info #790 CMake: Build tests/benchmark/benchmark.c as well for a build with -DEXPAT_BUILD_TESTS=ON #745 #757 docs: Document the importance of isFinal + adjust tests accordingly #736 docs: Improve use of "NULL" and "null" #713 docs: Be specific about version of XML (XML 1.0r4) and version of C (C99); (XML 1.0r5 will need a sponsor.) #762 docs: reference.html: Promote function XML_ParseBuffer more #779 docs: reference.html: Add HTML anchors to XML_* macros #760 docs: reference.html: Upgrade to OK.css 1.2.0 #763 #739 docs: Fix typos #696 docs|CI: Use HTTPS URLs instead of HTTP at various places #669 #670 .. #692 #703 .. #733 #772 Address compiler warnings #798 #800 Address clang-tidy warnings #775 #776 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 Infrastructure: #700 #701 docs: Document security policy in file SECURITY.md #766 docs: Improve parse buffer variables in-code documentation #674 #738 .. #740 #747 .. #748 #781 #782 Refactor coverage and conformance tests #714 #716 Refactor debug level variables to unsigned long #671 Improve handling of empty environment variable value in function getDebugLevel (without visible user effect) #755 #774 .. #758 #783 .. #784 #787 tests: Improve test coverage with regard to parse chunk size #660 #797 #801 Fuzzing: Improve fuzzing coverage #367 #799 Fuzzing|CI: Start running OSS-Fuzz fuzzing regression tests #698 #721 CI: Resolve some Travis CI leftovers #669 CI: Be robust towards absence of Git tags #693 #694 CI: Set permissions to "contents: read" for security #709 CI: Pin all GitHub Actions to specific commits for security #739 CI: Reject spelling errors using codespell #798 CI: Enforce clang-tidy clean code #773 #808 .. #809 #810 CI: Upgrade Clang from 15 to 18 #796 CI: Start using Clang's Control Flow Integrity sanitizer #675 #720 #722 CI: Adapt to breaking changes in GitHub Actions Ubuntu images #689 CI: Adapt to breaking changes in Clang/LLVM Debian packaging #763 CI: Adapt to breaking changes in codespell #803 CI: Adapt to breaking changes in Cppcheck Special thanks to: Ivan Galkin Joyce Brum Philippe Antoine Rhodri James Snild Dolkow spookyahell Steven Garske and Clang AddressSanitizer Clang UndefinedBehaviorSanitizer codespell GCC Farm Project OSS-Fuzz Sony Mobile ``` #### 2.6.1 ``` Release 2.6.1 Thu February 29 2024 Bug fixes: #817 Make tests independent of CPU speed, and thus more robust #828 #836 Expose billion laughs API with XML_DTD defined and XML_GE undefined, regression from 2.6.0 Other changes: #829 Hide test-only code behind new internal macro #833 Autotools: Reject expat_config.h.in defining SIZEOF_VOID_P #819 Address compiler warnings #832 #834 Version info bumped from 10:0:9 (libexpat*.so.1.9.0) to 10:1:9 (libexpat*.so.1.9.1); see https://verbump.de/ for what these numbers do Infrastructure: #818 CI: Adapt to breaking changes in clang-format Special thanks to: David Hall Snild Dolkow ``` #### 2.6.2 ``` Release 2.6.2 Wed March 13 2024 Security fixes: #839 #842 CVE-2024-28757 -- Prevent billion laughs attacks with isolated use of external parsers.

Added the
accept_http_if_already_terminated
to the SSL and OAuth 2.0 plugins to accept HTTP requests with aX-Forwaded-Proto: https
header when the request was supposed to be sent on HTTPs.X-Forwaded-Proto: https
. Now that check needs to be explicitly enabled only when the server cannot be reached from the outside, and the only point of entry is a Load Balancer that already terminates SSL.
