  - In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python
    API (Python bindings) because of an incorrect return value. This occurs in xmlPythonFileRead and
    xmlPythonFileReadRaw because of a difference between bytes and characters. (CVE-2025-32414)

  - 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
