CVE-2009-1436

Estado: ModificadaMedia (4.9)—💥 Exploit

The db interface in libc in FreeBSD 6.3, 6.4, 7.0, 7.1, and 7.2-PRERELEASE does not properly initialize memory for Berkeley DB 1.85 database structures, which allows local users to obtain sensitive information by reading a database file.

CVSS

Versión: 2.0
Vector: AV:L/AC:L/Au:N/C:C/I:N/A:N
Puntuación base: 4.9

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.89%
Percentil entre todas las CVEs puntuadas: 58
Fecha de la puntuación: 7/10/2026

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.
