CVE-2014-5207

Estado: ModificadaMedia (6.2)—💥 Exploit

fs/namespace.c en el kernel de Linux hasta 3.16.1 no restringe debidamente la limpieza MNT_NODEV, MNT_NOSUID, y MNT_NOEXEC y el cambio MNT_ATIME_MASK durante un remontaje de un montaje bind, lo que permite a usuarios locales ganar privilegios, interferir con copias de seguridad y auditoria en sistemas que tenían atime habilitado, o causar una denegación de servicio (la actualización excesiva de sistemas de ficheros) en sistemas que tenían atime deshabilitado a través de un comando 'mount -o remount' dentro de un espacio para el nombre del usuario.

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.
