CVE-2017-5596

Estado: ModificadaAlta (7.5)—

En Wireshark 2.2.0 hasta la versión 2.2.3 y 2.0.0 hasta la versión 2.0.9, el disector ASTERIX podría entrar en un bucle infinito, desencadenado por la inyección de paquetes o un archivo de captura mal formado. Esto fue abordado en epan/dissectors/packet-asterix.c cambiando un tipo de datos para evitar un desbordamiento de enteros.

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).
