Fedora 36: FEDORA-2022-d93b3bd8b9 Critical: mingw-expat Use-After-Free

fedora
Calendar Grey October 29, 2022
Dist Fedora Esm H88
Enhancements in mingw-expat 2.4.9 resolve a significant use-after-free vulnerability present in the XML parsing library.
Update to 2.4.9, fixes CVE-2022-30674.

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 to 2.4.9, fixes CVE-2022-30674.
