CVE-2009-2419

Estado: ModificadaMedia (4.3)—💥 Exploit

Vulnerabilidad de uso-después-de-liberación en la función servePendingRequests en WebCore en WebKit en Apple Safari v4.0 y v4.0.1 permite a atacantes remotos provocar una denegación de servicio (cuelgue de aplicación) o posiblemente ejecutar código arbitrario a través de un documento HTML elaborado que hace referencia a un fichero .js de longitud cero y la función JavaScript recarga (reload). NOTA: algunos de estos detalles se obtienen a partir de información de terceros.

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.
