CVE-2015-4497

Estado: ModificadaAlta (10)—

Vulnerabilidad de uso después de liberación de memoria en la implementación de CanvasRenderingContext2D en Mozilla Firefox en versiones anteriores a 40.0.3 y Firefox ESR 38.x en versiones anteriores a 38.2.1, permite a atacantes remotos ejecutar código arbitrario mediante el aprovechamiento de la interacción inadecuada entre los eventos de cambio de tamaño y los cambios en las secuencias de token Cascading Style Sheets (CSS) para un elemento CANVAS.

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).
