Estado: ModificadaMedia (6.8)—💥 Exploit
The StripTags function in (1) the USF decoder (modules/codec/subtitles/subsdec.c) and (2) the Text decoder (modules/codec/subtitles/subsusf.c) in VideoLAN VLC Media Player 1.1 before 1.1.6-rc allows remote attackers to execute arbitrary code via a subtitle with an opening "<" without a closing ">" in an MKV file, which triggers heap memory corruption, as demonstrated using refined-australia-blu720p-sample.mkv.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
- Puntuación base: 6.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 52%
- Percentil entre todas las CVEs puntuadas: 99
- Fecha de la puntuación: 7/10/2026
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).
💥 Exploits públicos
Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
