La función array_user_key_compare en PHP 4.4.6 y anteriores, y 5.X hasta la 5.2.1, hace una llamada erronea a zval_dtor, lo cual dispara una corrupción de memoria y permite a usuarios locales evitar el safe_mode y ejecutar código de su elección a través de ciertas operaciones de desasignación después de que array_user_key_compare haya sido llamada.

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.
