* Mon May 24 2021 pmonrealAATTsuse.com- 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 dimstarAATTopensuse.org- 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 dmuellerAATTsuse.com- 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.
* Other changes
