The remote host is missing a security patch for samba. It is, therefore, affected by a buffer overflow condition in the call_trans2open() function within file trans2.c due to improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit this, via an overly long string passed to the pname variable, to execute arbitrary code with the privileges of the server.
