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.

For the detailed security status of libxml2 please refer to its security tracker page at:
