CVE-2016-2839

Estado: ModificadaMedia (6.5)—

Mozilla Firefox en versiones anteriores a 48.0 y Firefox ESR 45.x en versiones anteriores a 45.3 en Linux hace llamadas cairo _cairo_surface_get_extents que no interactúan adecuadamente con asignación de cabecera libav en FFmpeg 0.10, lo que permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de un vídeo manipulado.

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).
