A flaw was found in FFmpeg's HLS playlist parsing. This vulnerability allows a denial of service via a maliciously crafted HLS playlist that triggers a null pointer dereference during initialization.

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.

Vulnerabilidad remota en FFmpeg (AV:N, PR:N, UI:N) explotable mediante archivo HLS malicioso, causando denegación de servicio por desreferencia de puntero nulo.

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.
