CVE-2016-9934

Estado: ModificadaAlta (7.5)—

ext/wddx/wddx.c en PHP en versiones anteriores a 5.6.28 y 7.x en versiones anteriores a 7.0.13 permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL) a través datos serializados manipulados en un documento wddxPacket XML, como se demuestra por una cadena PDORow.

CVSS
