CVE-2018-6358

Estado: ModificadaAlta (8.8)—

La función printDefineFont2 en util/listfdb.c en libming, hasta la versión 0.4.8, es vulnerable a un desbordamiento de búfer basado en memoria dinámica (heap), lo que puede permitir que los atacantes provoquen una denegación de servicio u otro tipo de impacto sin especificar mediante un archivo FDB 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).
