Samba 3.0.29 - 3.2.4 Potential Memory Disclosure

medium Nessus Plugin ID 34993

Language:

Synopsis

The remote Samba server may be affected by an information disclosure vulnerability.

Description

According to its banner, the version of the Samba server on the remote host is between 3.0.29 and 3.2.4 inclusive. Such versions reportedly can potentially leak arbitrary memory contents of the 'smbd' process due to a missing bounds check on client-generated offsets of secondary 'trans', 'trans2', and 'nttrans' requests.

Note that Nessus has not actually tried to exploit this issue or determine if the fix has been applied.

Solution

Upgrade to Samba version 3.2.5 / 3.0.33 or later or apply the appropriate patch referenced in the project's advisory.
