CVE-2016-5272

Estado: ModificadaAlta (8.8)—

La clase nsImageGeometryMixin en Mozilla Firefox en versiones anteriores a la 49.0, Firefox ESR en versiones 45.x anteriores a la 45.4 y Thunderbird en versiones anteriores a la 45.4 no devuelve correctamente una variable no especificada durante el manejo de los elementos INPUT, lo que permite que los atacantes remotos ejecuten código arbitrario mediante un sitio web 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).
