CVE-2016-2819

Estado: ModificadaAlta (8.8)—💥 Exploit

Desbordamiento de buffer basado en memoria dinámica en Mozilla Firefox en versiones anteriores a 47.0 y Firefox ESR 45.x en versiones anteriores a 45.2 permite a atacantes remotos ejecutar código arbitrario a través de fragmentos HTML5 de contexto extranjero, tal como se demuestra mediante fragmentos dentro de un elemento SVG.

CVSS

Versión: 3.0
Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Puntuación base: 8.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 24%
Percentil entre todas las CVEs puntuadas: 98
Fecha de la puntuación: 10/10/2026

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.
