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 3.4.0. It is, therefore, affected by a remote code execution vulnerability in process.c due to a heap-based buffer overflow. An unauthenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands via Batched / AndX request.

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 3.4.0 or later.
