A remote attacker could exploit this vulnerability by providing a specially crafted XML document containing a Document Type Definition (DTD) with enumerated attribute values.

This flaw can lead to a denial of service (DoS) due to a reproducible crash in Python applications using the libxml2 SAX bindings."}], "lastModified": "2026-10-30T01:16:46.517", "sourceIdentifier": "secalert@redhat.com"}
