Desbordamiento de enteros en PHP 5 hasta la 5.1.6 y 4 anteriorer a 4.3.0 permite a un atacante remoto ejecutar código de su elección a través de un argumento a la funcion PHP unserializable con un valor grande para el número de elementos del array, lo cual dispara el desbordamiento en la función ecalloc en Zend Engine (Zend/zend_alloc.c).

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).

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
