Estado: ModificadaMedia (4.3)—💥 Exploit

Firefox de Mozilla versiones 3.0.8 y anteriores a 3.0.x, permite a los atacantes remotos causar una denegación de servicio (corrupción de memoria) por medio de un documento XML compuesto por una serie larga de etiquetas de inicio sin las etiquetas finales correspondientes. NOTA: más tarde se informó que la versión 3.0.10 y anteriores también están afectadas.

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).

💥 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.
