    * CVE-2025-32414: fix out-of-bounds memory access
    * CVE-2025-32415: fix heap buffer overflow in xmlSchemaIDCFillNodeTables
    CVE(s):
    CVE-2025-32414
    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-2025-32415
    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.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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