Fedora 38: FEDORA-2024-b8656bc059 Critical: DoS Issues in mingw-expat

fedora
Calendar Grey February 25, 2024
Dist Fedora Esm H88
The upgrade to mingw-expat version 2.6.0 addresses several parsing errors and mitigates possible DoS vulnerabilities in Fedora 38.
Update to 2.6.0, fixes CVE-2023-52425, CVE-2023-52426.

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 2.6.0, fixes CVE-2023-52425, CVE-2023-52426.
