CVE-2016-7133

Estado: ModificadaAlta (8.1)—

Zend/zend_alloc.c en PHP 7.x en versiones anteriores a 7.0.10, cuando la apertura de open_basedir está habilitada, no maneja adecuadamente operaciones de realloc enormes, lo que permite a atacantes remotos provocar una denegación de servicio (desbordamiento de entero) o tener otro posible impacto no especificado a través de un nombre de ruta largo.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
