NVD Description
Note: Versions mentioned in the description apply only to the upstream libxml2-devel package and not the libxml2-devel package as distributed by RHEL.
A flaw was found in libxml2. A local user or an attacker providing a specially crafted XML catalog can trigger a NULL pointer dereference during XML catalog parsing. This occurs when a nextCatalog element lacks its mandatory catalog attribute, leading to the application crashing and causing a Denial of Service (DoS).
