CVE-2016-6832

Estado: ModificadaMedia (5.5)—

Desbordamiento de búfer basado en memoria dinámica en la función ff_audio_resample en resample.c en libav en versiones anteriores a 11.4 permite a atacantes remotos provocar una denegación de servicio (caída) a través de vectores relacionados con redimensionamiento de búfer.

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).
