Paquetes afectados:
clamav
Vulnerable:
Referencias a bases de datos de seguridad:
En el sistema de seguimiento de errores de Debian: error 320014.
En la base de datos de Bugtraq (en SecurityFocus): Id. en BugTraq 16191.
En el diccionario CVE de Mitre: CVE-2006-0162.
Información adicional:

Se ha descubierto un desbordamiento de pila en ClamAV, el analizador de virus, que podía permitir que un atacante ejecutase código arbitrario enviando un ejecutable codificado para UPX manipulado a un sistema en el que estuviese funcionando ClamAV. Además, se han corregido otros potenciales desbordamientos.

No había disponibles paquetes para la arquitectura ARM cuando se publicó DSA 947-1, y ahora sí que están disponibles. También, en DSA 947-1, se identificaba incorrectamente la versión del paquete que corregía estas incidencias en la distribución inestable (sid).

La distribución estable anterior (woody) no incluye ClamAV.

Para la distribución estable (sarge), este problema se ha corregido en la versión 0.84-2.sarge.7.

Para la distribución inestable (sid), este problema se ha corregido en la versión 0.88-1.

Le recomendamos que actualice inmediatamente el paquete clamav.

Arreglado en:

Debian GNU/Linux 3.1 (sarge)
