expat-2.5.0-1.el9_3.1

This is expat, the C library for parsing XML, written by James Clark. Expat is a stream oriented XML parser. This means that you register handlers with the parser prior to starting the parse. These handlers are called when the parser discovers the associated structures in the document being parsed. A start tag is an example of the kind of structures for which you may register handlers.

Security Fix(es):

* expat: parsing large tokens can trigger a denial of service (CVE-2023-52425)
* expat: XML Entity Expansion (CVE-2024-28757)

CVE-2023-52425
libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are required in the case of a large token for which multiple buffer fills are needed.
CVE-2024-28757
libexpat through 2.6.1 allows an XML Entity Expansion attack when there is isolated use of external parsers (created via XML_ExternalEntityParserCreate).
