Samba < 3.4.8 / 3.5.2 Session Setup AndX DoS

medium Nessus Plugin ID 46351

Language:

Synopsis

The remote service is vulnerable to denial of service attacks.

Description

According to its banner, the version of Samba installed on the remote host is a version of 3.4 before 3.4.8 or 3.5 < 3.5.2. Such versions are affected by two denial of service vulnerabilities that can be triggered via either a NULL pointer dereference or an uninitialized variable read.

By sending specially crafted 'Session Setup AndX' requests, an unauthenticated, remote attacker can exploit these vulnerabilities to crash the affected service, thereby denying service to legitimate users.

Solution

Upgrade to Samba 3.4.8 / 3.5.2 or later.
