    In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap-     based buffer under-read. To exploit this, a crafted XML document must be validated against an XML schema     with certain identity constraints, or a crafted XML schema must be used. (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.

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