CVE-2017-12464

Estado: ModificadaAlta (7.5)—

ccn-lite-valid.c en CCN-lite, en versiones anteriores a la 2.00, permite que atacantes dependientes del contexto provoquen una denegación de servicio (desreferencia de puntero NULL) mediante vectores relacionados con la variable keyfile.

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).
