Package : libxml2
CVE ID : CVE-2025-7425
Debian Bug : 1109122
A flaw was found in libxslt, the XSLT 1.0 processing library, where the
attribute type, atype, flags are modified in a way that corrupts internal
memory management. This is addressed by adding guards in libxml2, the
GNOME XML library, preventing the heap use-after-free from happening.
For the oldstable distribution (bookworm), this problem has been fixed
in version 2.9.14+dfsg-1.3~deb12u4.
For the stable distribution (trixie), this problem has been fixed in
version 2.12.7+dfsg+really2.9.14-2.1+deb13u1.
We recommend that you upgrade your libxml2 packages.
