Samba < 3.0.37 / 3.2.15 / 3.3.8 / 3.4.2 Multiple Vulnerabilities

Medium Nessus Network Monitor Plugin ID 5194

Synopsis

The remote Samba server is vulnerable to multiple attack vectors.

Description

According to its banner, the version of Samba server on the remote host is potentially affected by multiple vulnerabilities :

- 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 filesystem 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.
