CVE-2017-1000375

Estado: ModificadaCrítica (9.8)—💥 Exploit

NetBSD asigna el editor de enlace del tiempo de ejecución del archivo ld.so directamente debajo de la región stack, incluso si ASLR está habilitada, esto permite a los atacantes manipular más fácilmente la memoria, lo que conlleva a la ejecución de código arbitraria. Esto afecta a NetBSD versión 7.1 y anteriores.

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).

💥 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.
