CVE-2018-11100

Estado: ModificadaAlta (8.8)—

La función decompileSETTARGET en decompile.c en libming hasta la versión 0.4.8 gestiona de manera incorrecta los casos en los que la cabecera indica que el tamaño de un archivo es mayor que el tamaño real, lo que permite que los atacantes remotos provoquen una denegación de servicio (fallo de segmentación y cierre inesperado) o, posiblemente, otro impacto no especificado.

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).
