CVE-2024-35366

Estado: AnalizadaCrítica (9.1)—

FFmpeg n6.1.1 is Integer Overflow. The vulnerability exists in the parse_options function of sbgdec.c within the libavformat module. When parsing certain options, the software does not adequately validate the input. This allows for negative duration values to be accepted without proper bounds checking.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

FFmpeg accesible en red sin autenticación (AV:N/PR:N); integer overflow en parse_options causa DoS. Impacto: availability (A:H) por valores de duración negativos.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
