CVE-2018-6156

Estado: ModificadaAlta (8.8)—

La derivación incorrecta de la longitud de un paquete en WebRTC en Google Chrome antes de 68.0.3440.75 permitió que un atacante remoto pudiera explotar la corrupción del montón a través de un archivo de video diseñado.

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).
