The remote Samba server is affected by a buffer overflow attack vector.
According to its banner, the version of Samba is 2.2.x earlier than 2.2.10, or 3.0.x earlier than 3.0.5, and is therefore affected by a flaw related to setting the option 'mangling method' to 'hash' in 'smb.conf' (which is not the default setting), and may allow an attacker to cause a buffer overflow. No further details have been provided.
Upgrade Samba to version 3.0.5 or later. If version 3.0.x cannot be obtained, version 2.2.10 has also been patched for this issue.
