CVE-2011-3483

Estado: ModificadaMedia (4.3)—💥 Exploit

Wireshark v1.6.x antes de v1.6.2, permite a atacantes remotos causar una denegación de servicio (caída de la aplicación) a través de un archivo de captura modificado que provoca un tvbuff root inválido, relacionado con una "vulnerabilidad de manejo de excepción 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).

💥 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.
