Expat 2.6.3 released, includes security fixes

September 4, 2024

Submitted by Sebastian Pipping.

For readers new to Expat:

libexpat is a fast streaming XML parser. Alongside libxml2, Expat is one of the most widely used software libre XML parsers written in C, specifically C99. It is cross-platform and licensed under the MIT license.

Expat 2.6.3 has been released earlier today. The key motivation for cutting a release and cutting it now are the three security findings by TaiYou that were assigned identifiers CVE-2024-45490, CVE-2024-45491 and CVE-2024-45492.

Out of the remaining bunch of fixes in and around the build system, the BSD-motivated portability contributions by Dag-Erling Smørgrav stand out with this release. Thanks to everyone who contributed to this release of Expat!

For more details about this release, please check out the change log.

If you maintain Expat packaging or a bundled copy of Expat or a pinned version of Expat somewhere, please update to 2.6.3. Thank you!
