HP Software Security Response Team

REFERENCES:    CAN-2004-0686

A potential security vulnerability has been identified with HP-UX
running the CIFS Server.  This buffer overflow could potentially
be exploited remotely to gain root access.

SUPPORTED SOFTWARE VERSIONS*:  ONLY impacted versions are listed.
HP-UX B.11.00, B.11.11, B.11.22, B.11.23.
For a PGP signed version of this bulletin
please write to


Note: To determine if a system has an affected version,
      search the output of "swlist -a revision -l fileset"
      for an affected fileset.  Then determine if the
      recommended patch or update is installed.

HP-UX B.11.23
HP-UX B.11.11
HP-UX B.11.00
For revision A.01.11.01 and previous:
 ->action: update to revision A.01.11.02 or subsequent.

 ->HP-UX B.11.22
For revision A.01.11.01 and previous:
 ->action: Please see the Resolution section.


Note: The HP CIFS Server versions do not map directly to
         original Samba versions.  The what(1) output will show
         the HP version string, for example: A.01.11.02.  Samba
         commands such as "smbd -V" or "smbstatus" will report the
         underlying base Samba version, for example: 2.2.10.

Note: The HP CIFS Server versions A.01.11.02 and previous are
      not affected by the vulnerability reported in CAN-2004-0600.

 ->For HP-UX B.11.00, B.11.11 and B.11.23
 ->HP has made updates available from
 ->CIFS Server 2.2j version A.01.11.02 eliminates the
 ->potential vulnerability.

 ->For HP-UX B.11.22 the potential vulnerability can be
avoided by setting "mangling method = hash2" or
"mangled names = no" in smb.conf.

Note: CIFS Server installations requiring the hash mangling
      method must evaluate the impact of converting to the
      hash2 mangling method.

MANUAL ACTIONS:  Yes - Update plus other actions
