Calendar Grey September 14, 2024
Scroller Fedora
Essential patches for Fedora 40's mingw-expat to rectify several parsing security flaws. Discover further details here.
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.
