Ubuntu 24.04: libxml2 Critical XML Processor Upgrade 2025-72af94d3b12

fedora
Calendar Grey September 19, 2025
Dist Fedora Esm H88
Significant patch for Fedora 42 addressing expat library to resolve major XML processing concerns.
Rebase to 2.7.2

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.
