CVE-2016-4077

Estado: ModificadaMedia (5.9)—

epan/reassemble.c en TShark en Wireshark 2.0.x en versiones anteriores a 2.0.3 confía en el manejo incorrecto de casos especiales de estructuras de datos Tvb truncadas, lo que permite a atacantes remotos provocar una denegación de servicio (uso después de liberación de memoria y caída de aplicación) a través de un paquete manipulado.

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).
