"According to its version number, the remote Samba server is affected
by several flaws :

  - A denial of service issue occuring if an authenticated
    attacker sends a large number of CIFS session requests
    which will cause an infinite loop to occur in the smbd
    daemon, thus utilizing CPU resources and denying access
    to legitimate users ;

  - A remote format string vulnerability that could be
    exploited by an attacker with write access to a remote
    share by sending a malformed request to the remote
    service (this issue only affects installations sharing
    an AFS file system when the afsacl.so VFS module is
    loaded)

  - A remote buffer overflow vulnerability affecting the NSS
    lookup capability of the remote winbindd daemon");
