MinGW Expat update to 2.7.5 addresses denial of service issue in Fedora 42, ensuring better XML parsing.
Update to 2.7.5.

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 2.7.5.
