CVE-2006-3493

Estado: ModificadaMedia (5.1)—💥 Exploit

Desbordamiento de búfer en la función LsCreateLine (mso_203) en mso.dll y mso9.dll, tal como se utiliza en Microsoft Word y posiblemente en otros productos en Microsoft Office 2003, 2002 y 2000, permite a atacantes remotos asistidos por usuario provocar una denegación de servicio (caída) a través de un documento Word manipulado u otro tipo de archivo Office. NOTA: este problema fue originalmente reportado para permitir ejecución de código, pero el 10-07-2006 Microsoft declaró que la ejecución de código no es posible y el investigador original está de acuerdo.

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.
