CVE-2006-3746

Estado: ModificadaMedia (5)—💥 Exploit
Desbordamiento de búfer de enteros en parse_comment en GnuPG (gpg) 1.4.4 permite a atacantes remotos provocar denegación de servicio (fallo de segmentación) a través de un mensaje manipulado.
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: 7.21%
Percentil entre todas las CVEs puntuadas: 94
Fecha de la puntuación: 9/10/2026
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.
