Changelog for libexpat1-2.6.3-lp155.225.1.x86_64.rpm :

* Thu Sep 26 2024 pgajdosAATTsuse.com- updated keyring [https://build.suse.de/request/show/345282]- modified sources % expat.keyring
* Thu Sep 05 2024 David Anes - 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.

* Reject direct parameter entity recursion and avoid the related undefined behavior
* Fri Mar 01 2024 Andreas Stieger - 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 - 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
* Mon Feb 12 2024 David Anes - 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) - - 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

*+,;=
* Other changes: - CMake|Windows: Store Expat version in the DLL - Document consequences of namespace separator choices not just in doc/reference.html but also in header - Document Expat\'s lack of validation of namespace URIs against RFC 3986, and that the XML 1.0r4 specification doesn\'t require Expat to validate namespace URIs, and that Expat may do more in that regard in future releases. If you find need for strict RFC 3986 URI validation on application level today, https://uriparser.github.io/ may be of interest. - Fix documentation of XML_EndDoctypeDeclHandler in - Document that a call to XML_FreeContentModel can be done at a later time from outside the element declaration handler - Make hardcoded namespace URIs easier to find in code - Update documentation on use of XML_POOR_ENTOPY on Solaris - tests: Resolve use of macros NAN and INFINITY for GNU G++ 4.8.2 on Solaris. - Version info bumped from 9:6:8 to 9:7:8; see https://verbump.de/ for what these numbers do

* Security fixes: - CVE-2022-25235 -- Passing malformed 2- and 3-byte UTF-8 sequences (e.g. from start tag names) to the XML processing application on top of Expat can cause arbitrary damage (e.g. code execution) depending on how invalid UTF-8 is handled inside the XML processor; validation was not their job but Expat\'s. Exploits with code execution are known to exist. - CVE-2022-25236 -- Passing (one or more) namespace separator characters in \"xmlns[:prefix]\" attribute values made Expat send malformed tag names to the XML processor on top of Expat which can cause arbitrary damage (e.g. code execution) depending on such unexpectable cases are handled inside the XML processor; validation was not their job but Expat\'s. Exploits with code execution are known to exist. - CVE-2022-25313 -- Fix stack exhaustion in doctype parsing that could be triggered by e.g. a 2 megabytes file with a large number of opening braces. Expected impact is denial of service or potentially arbitrary code execution. - CVE-2022-25314 -- Fix integer overflow in function copyString; only affects the encoding name parameter at parser creation time which is often hardcoded (rather than user input), takes a value in the gigabytes to trigger, and a 64-bit machine. Expected impact is denial of service. - CVE-2022-25315 -- Fix integer overflow in function storeRawNames; needs input in the gigabytes and a 64-bit machine. Expected impact is denial of service or potentially arbitrary code execution.

Impact is denial of service or more. - CVE-2022-23990 -- Fix unsigned integer overflow in function doProlog triggered by large content in element type declarations when there is an element declaration handler present (from a prior call to XML_SetElementDeclHandler). Impact is denial of service or more.

Impact is denial of service, or more.
* CVE-2021-46143 (ZDI-CAN-16157) -- Fix integer overflow on variable m_groupSize in function doProlog leading to realloc acting as free. Impact is denial of service or more.

* Mon May 24 2021 Pedro Monreal - Update to 2.4.0: [CVE-2013-0340 \"Billion Laughs\"]
* Security fixes: - CVE-2013-0340/CWE-776 -- Protect against billion laughs attacks (denial-of-service; flavors targeting CPU time or RAM or both, leveraging general entities or parameter entities or both) by tracking and limiting the input amplification factor ( := ( + ) / ). By conservative default, amplification up to a factor of 100.0 is tolerated and rejection only starts after 8 MiB of output bytes (= + ) have been processed. The fix adds the following to the API: - A new error code XML_ERROR_AMPLIFICATION_LIMIT_BREACH to signals this specific condition. - Two new API functions .. - XML_SetBillionLaughsAttackProtectionMaximumAmplification and - XML_SetBillionLaughsAttackProtectionActivationThreshold .. to further tighten billion laughs protection parameters when desired. Please see file \"doc/reference.html\" for details. If you ever need to increase the defaults for non-attack XML payload, please file a bug report with libexpat. - Two new XML_FEATURE_
* constants .. - that can be queried using the XML_GetFeatureList function, and - that are shown in \"xmlwf -v\" output. - Two new environment variable switches .. - EXPAT_ACCOUNTING_DEBUG=(0|1|2|3) and - EXPAT_ENTITY_DEBUG=(0|1) .. for runtime debugging of accounting and entity processing. Specific behavior of these values may change in the future. - Two new command line arguments \"-a FACTOR\" and \"-b BYTES\" for xmlwf to further tighten billion laughs protection parameters when desired. If you ever need to increase the defaults for non-attack XML payload, please file a bug report with libexpat.
* Bug fixes: - For (non-default) compilation with -DEXPAT_MIN_SIZE=ON (CMake) or CPPFLAGS=-DXML_MIN_SIZE (GNU Autotools): Fix segfault for UTF-16 payloads containing CDATA sections. - Autotools: Fix generated CMake files for non-64bit and non-Linux platforms (e.g. macOS and MinGW in particular) that were introduced with release 2.3.0

* Tue Apr 13 2021 Dominique Leuenberger - Do not BuildRequire cmake: expat is part of the distro bootstrap cycle and any additional dependency makes the ring larger. In this case here, cmake was even only used to own a directory.
* Tue Apr 06 2021 Dirk Müller - update to 2.3.0:
* When calling XML_ParseBuffer without a prior successful call to XML_GetBuffer as a user, no longer trigger undefined behavior (by adding an integer to a NULL pointer) but rather return XML_STATUS_ERROR and set the error code to (new) code XML_ERROR_NO_BUFFER. Found by UBSan (UndefinedBehaviorSanitizer) of Clang 11 (but not Clang 9).
* xmlwf: Exit status 2 was used for both: - malformed input files (documented) and - invalid command-line arguments (undocumented). case of invalid command-line arguments now has its own exit status 4, resolving the ambiguity.
