The version of Samba running on the remote host is prior to 2.2.8a. It is, therefore, affected by a remote code execution vulnerability in the SMB/CIFS packet fragment re-assembly code in smbd. An unauthenticated, remote attacker can exploit this to inject binary specific exploit code into smbd and gain root access on a Samba serving system.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
