CVE-2015-8721

Estado: ModificadaMedia (5.5)—

Desbordamiento de buffer en la función tvb_uncompress en epan/tvbuff_zlib.c en Wireshark 1.12.x en versiones anteriores a 1.12.9 y 2.0.x en versiones anteriores a 2.0.1 permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de un paquete con compresión zlib 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).
