CVE-2014-1564

Estado: ModificadaMedia (4.3)—💥 Exploit

Mozilla Firefox before 32.0, Firefox ESR 31.x before 31.1, and Thunderbird 31.x before 31.1 do not properly initialize memory for GIF rendering, which allows remote attackers to obtain sensitive information from process memory via crafted web script that interacts with a CANVAS element associated with a malformed GIF image.

CVSS

Versión: 2.0
Vector: AV:N/AC:M/Au:N/C:P/I:N/A:N
Puntuación base: 4.3

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 5.46%
Percentil entre todas las CVEs puntuadas: 93
Fecha de la puntuación: 6/10/2026

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
