CVE-2016-6520

Estado: ModificadaCrítica (9.1)—

Desbordamiento de búfer en MagickCore/enhance.c en ImageMagick en versiones anteriores a 7.0.2-7 permite a atacantes remotos tener un impacto no especificado a través de vectores relacionados con morfología de caché de píxeles.

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).
