Synopsis

The remote Samba server is affected by a denial of service vulnerability.

Description

According to its banner, the version of Samba running on the remote host is 3.x prior to 3.5.22, 3.6.x prior to 3.6.17 or 4.0.x prior to 4.0.8. It is, therefore, potentially affected by a denial of service vulnerability.

An integer overflow error exists in the function 'read_nttrans_ea_lis' in the file 'nttrans.c' that could allow denial of service attacks to be carried out via specially crafted network traffic.

Note if 'guest' connections are allowed, this issue can be exploited by a remote, unauthenticated attacker.

Further note that Nessus has relied only on the self-reported version number and has not actually tried to exploit this issue or determine if the associated patch has been applied.

Solution

Either install the patch referenced in the project's advisory, or upgrade to version 3.5.22 / 3.6.17 / 4.0.8 or later.
