Patch Published: 2008-08-26
CVE [?]: CVE-2003-0196, CVE-2003-0201
CPE [?]: cpe:/a:samba:samba
Exploited by Malware: True

Synopsis

The remote Samba server is affected by a remote code execution vulnerability.

Description

The version of Samba running on the remote host is prior to 2.2.8a. It is, therefore, affected by a remote code execution vulnerability in the SMB/CIFS packet fragment re-assembly code in smbd. An unauthenticated, remote attacker can exploit this to inject binary specific exploit code into smbd and gain root access on a Samba serving system.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Samba version 2.2.8a or later.
