Descriptions

libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails. This occurs in xmlUnlinkNode in tree.c. NOTE: the vendor's position is "I don't think these issues are critical enough to warrant a CVE ID ... because an attacker typically can't control when memory allocations fail."

** EN DISPUTA ** libxml2 hasta 2.11.5 tiene un use-after-free que solo puede ocurrir después de que falla una determinada asignación de memoria. Esto ocurre en xmlUnlinkNode en tree.c. NOTA: la posición del proveedor es "No creo que estos problemas sean lo suficientemente críticos como para justificar un ID CVE... porque un atacante normalmente no puede controlar cuándo fallan las asignaciones de memoria".
