CVE-2017-16546

Estado: ModificadaAlta (8.8)—

La función ReadWPGImage en coders/wpg.c en ImageMagick 7.0.7-9 no valida correctamente el índice de mapa de colores en una paleta WPG, lo que permite que atacantes remotos provoquen una denegación de servicio (uso de datos no inicializados o asignación de memoria no válida) o, posiblemente, causen otros impactos no especificados mediante un archivo WPG mal formada.

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).
