- Referencias a bases de datos de seguridad:
- En la base de datos de Bugtraq (en SecurityFocus): Id. en BugTraq 7107, Id. en BugTraq 7106.
En el diccionario CVE de Mitre: CVE-2003-0085, CVE-2003-0086. - Información adicional:
-
Sebastian Krahmer, del equipo de la auditoría de seguridad de SuSE, encontró dos problemas en samba, una popular implementación de SMB/CIFS. Los problemas son:
- un desbordamiento de búfer en el paquete SMB/CIFS fragmentaba el código de reensamblado usado por smbd. Ya que smbd corre como root, un atacante podía usar esto para obtener acceso como root a una máquina que estuviera corriendo smbd.
- el código para escribir archivos reg era vulnerable por una fuga en chown que hacía posible que un usuario local escribiera archivos del sistema.
Ambos problemas se han corregido en la versión 2.2.8 y en la versión 2.2.3a-12.1 del paquete para Debian GNU/Linux 3.0/woody.
- Arreglado en:
-
Debian GNU/Linux 3.0 (woody)
