CVE-2011-3266

Estado: ModificadaBaja (2.6)—

La función proto_tree_add_item en Wireshark v1.6.1, cuando el protocolo IKEv1 disector se utiliza, permite a atacantes remotos asistidos por el usuario provocar una denegación de servicio (bucle infinito) a través de vectores que implican un paquete IKE malformado y muchos artículos en un árbol.

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).
