CVE-2006-2971

Estado: ModificadaMedia (5)—💥 Exploit

Desbordamiento de entero en la función recv_packet de 0verkill 0.16 permite a atacantes remotos provocar una denegación de servicio (caída del demonio) mediante un paquete UDP de menos de 12 bytes, lo que da lugar a un valor de longitud grande en la función crc32.

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.
