samba - exploitable buffer overruns

Package(s):samba CVE #(s):CAN-2003-0085 CAN-2003-0086
Created:March 17, 2003 Updated:April 4, 2003
Description: The SuSE security audit team, in particular Sebastian Krahmer has found a flaw in the Samba main smbd code which could allow an external attacker to remotely and anonymously gain Super User (root) privileges on a server running a Samba server.

This flaw exists in previous versions of Samba from 2.0.x to 2.2.7a inclusive. This is a serious problem and all sites should either upgrade to Samba 2.2.8 immediately or prohibit access to TCP ports 139 and 445. Advice created by Andrew Tridgell, the leader of the Samba Team, on how to protect an unpatched Samba server is given at the end of this section.

The SMB/CIFS protocol implemented by Samba is vulnerable to many attacks, even without specific security holes. The TCP ports 139 and the new port 445 (used by Win2k and the Samba 3.0 alpha code in particular) should never be exposed to untrusted networks.

See this article for more information. Samba-TNG users should update to version 0.3.1.
