Synopsis

The remote Samba server may be affected by multiple vulnerabilities.

Description

According to its banner, the version of Samba server on the remote host is earlier than 3.0.37 / 3.2.15 / 3.3.8 / 3.4.2. Such versions are potentially affected by multiple issues :

- If a user in '/etc/passwd' is misconfigured to have an empty home directory, then connecting to the home share of this user will use the root of the file system as the home directory. (CVE-2009-2813)

- Specially crafted SMB requests on authenticated SMB connections can send smbd into a 100% loop, causing a denial of service. (CVE-2009-2906)

- When 'mount.cifs' is installed as a setuid program, a user can pass it a credential or password path to which he or she does not have access and then use the '--verbose' option to view the first line of that file.
(CVE-2009-2948)

Solution

Upgrade to Samba 3.0.37 / 3.2.15 / 3.3.8 / 3.4.2 or later.
