CVE-2018-11251

Estado: ModificadaMedia (6.5)—

Hay una sobrelectura de búfer basada en memoria dinámica (heap) en ImageMagick 7.0.7-23 Q16 x86_64 2018-01-24, en ReadSUNImage en coders/sun.c que permite que atacantes provoquen una denegación de servicio (cierre inesperado de la aplicación en SetGrayscaleImage en MagickCore/quantize.c) mediante un archivo de imagen SUN 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).
