Fedora 41: 2024-c5d55d5845 Critical: mingw-expat Parsing Issues

fedora
Calendar Grey September 13, 2024
Dist Fedora Esm H88
Upgrade to mingw-expat version 2.6.3 addresses significant vulnerabilities for improved safety in Fedora environments.
Update to expat-2.6.3.

Summary

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.

Update Information:

Update to expat-2.6.3.
