CVE-2016-4563

Estado: ModificadaAlta (8.8)—

La función TraceStrokePolygon en MagickCore/draw.c en ImageMagick en versiones anteriores a 6.9.4-0 y 7.x en versiones anteriores a 7.0.1-2 no maneja correctamente la relación entre el valor BezierQuantum y ciertos trazos de datos, lo que permite a atacantes remotos provocar una denegación de servicio (desbordamiento de buffer y caída de aplicación) o posiblemente tener otro impacto no especificado a través de un archivo 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).
