CVE-2006-0747

Estado: ModificadaMedia (5)—💥 Exploit

Desbordamiento por defecto (underflow) de enteros en Freetype anterior a 2.2 permite a atacantes remotos provocar una denegación de servicio (caída) mediante un archivo de fuente con un número impar de valores de azul (blue values), lo que provoca el desbordamiento por defecto al decrementar en 2 en un contexto que asume un número par de valores.

CVSS

Versión: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
Puntuación base: 5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 13%
Percentil entre todas las CVEs puntuadas: 96
Fecha de la puntuación: 13/10/2026

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.
