Package : libxml2 Version : 2.9.10+dfsg-6.7+deb11u7 CVE ID : CVE-2025-32414 CVE-2025-32415

Two issues have been found in libxml2, the GNOME XML library.
Thy are related to an out-of-bounds memory access in the Python API and a heap-buffer-overflow in xmlSchemaIDCFillNodeTables().

For Debian 11 bullseye, these problems have been fixed in version 2.9.10+dfsg-6.7+deb11u7.

We recommend that you upgrade your libxml2 packages.
