libxml2/libxml2-2.12.5-CVE-2025-7425.patch
David King b83a60bb88 Fix CVE-2025-7425 (RHEL-102794) 
The patch is adapted from the Apple-provided version upstream: https://gitlab.gnome.org/GNOME/libxslt/-/issues/139

As the Apple fork was a substantially different version, there were some
significant changes to the patch.

Resolves: RHEL-102794

Subject: [PATCH] libxslt: heap-use-after-free in xmlFreeID caused by `atype`
corruption
* include/libxml/tree.h:
(XML_ATTR_CLEAR_ATYPE): Add.
(XML_ATTR_GET_ATYPE): Add.
(XML_ATTR_SET_ATYPE): Add.
(XML_NODE_ADD_EXTRA): Add.
(XML_NODE_CLEAR_EXTRA): Add.

(XML_NODE_SET_EXTRA): Add.
(XML_DOC_ADD_PROPERTIES): Add.
(XML_DOC_CLEAR_PROPERTIES): Add.
(XML_DOC_GET_PROPERTIES): Add.
(XML_DOC_SET_PROPERTIES): Add.
- Add macros for accessing fields with upper bits that may be set by
libxslt.
* HTMLparser.c:
(htmlNewDocNoDtD):
* SAX2.c:
(xmlSAX2StartDocument):
(xmlSAX2EndDocument):
* parser.c:

- Adopt macros by renaming the struct fields, recompiling and fixing
compiler failures, then changing the struct field names back.
