Fecha del informe:
22 de nov de 2002
Paquetes afectados:
samba
Vulnerable:
Referencias a bases de datos de seguridad:
En el diccionario CVE de Mitre: CVE-2002-1318.
Información adicional:

Steve Langasek encontró un error explotable en el código de gestión de contraseñas en Samba: al convertir desde el código de página de DOS a Unicode little endian UCS2, no se verificaba la longitud del búfer y podía ocurrir un desbordamiento. No hay ningún programa conocido que se aproveche de esto, pero se recomienda encarecidamente una actualización.

Este problema ha sido corregido en la versión 2.2.3a-12 de los paquetes Samba de Debian y en la versión 2.2.7 del autor.

Arreglado en:

Debian GNU/Linux 3.0 (woody)
