Descriptions

The php_wddx_push_element function in ext/wddx/wddx.c in PHP before 5.6.26 and 7.x before 7.0.11 allows remote attackers to cause a denial of service (invalid pointer access and out-of-bounds read) or possibly have unspecified other impact via an incorrect boolean element in a wddxPacket XML document, leading to mishandling in a wddx_deserialize call.

La función php_wddx_push_element en ext/wddx/wddx.c en PHP en versiones anteriores a 5.6.26 y 7.x en versiones anteriores a 7.0.11 permite a atacantes remotos provocar una denegación de servicio (acceso a puntero no válido y lectura fuera de límites) o tener otro posible impacto no especificado a través de un elemento booleano incorrecto en un documento XML wddxPacket, produciendo una manejo incorrecto en una llamada wddx_deserialize.
