CVE-2015-4644
Estado: ModificadaAlta (7.5)—
La función php_pgsql_meta_data en pgsql.c en la extensión PostgreSQL (también conocida como pgsql) en PHP en versiones anteriores a 5.4.42, 5.5.x en versiones anteriores a 5.5.26 y 5.6 en versiones anteriores a 5.6.10 no tiene una extración de contador válido para nombres de tabla, lo que podría permitir a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL y caída de aplicación) a través de un nombre manipulado. NOTA: esta vulnerabilidad existe debido a una solución incompleta de CVE-2015-1352.
