    SSRT4885 rev.0 - HP-UX CIFS Server (Samba) remote code execution,
                     Denial of Service (DoS)

    NOTICE:
    There are no restrictions for distribution of this Security
    Bulletin provided that it remains complete and intact.

    The information in this Security Bulletin should be acted upon
    as soon as possible.

    INITIAL RELEASE:
    02 February 2005

    POTENTIAL SECURITY IMPACT:
    Remote arbitarary code execution, Denial of Service (DoS).

    SOURCE:
    Hewlett-Packard Company
    HP Software Security Response Team

    VULNERABILITY SUMMARY:
    A potential security vulnerability has been identified with HP-UX
    running CIFS Server (Samba). This vulnerability could potentially
    allow a remote unauthenticated user to cause controllable heap
    corruption, leading to execution of arbitrary commands with
    root privileges, or a Denial of Service (DoS).

    REFERENCES:
    CAN-2004-1154

    SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.
    HP-UX B.11.00, B.11.11, B.11.22, and B.11.23.

    BACKGROUND:

    AFFECTED VERSIONS

    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 fileset is installed.

    HP-UX B.11.00
    HP-UX B.11.11
    HP-UX B.11.22
    HP-UX B.11.23
    ============
    For version A.01.11.03 and previous
    CIFS-Server
    action: update to revision A.01.11.04 or subsequent

    HP-UX B.11.11
    HP-UX B.11.23
    ============
    For version A.02.01
    CIFS-Server
    action: update to revision A.02.01.01 or subsequent

    END AFFECTED VERSIONS

    NOTE:
       The HP CIFS Server versions do not map directly to
       the original Samba versions. The what(1) output will
       show the HP-UX version string, for example: A.01.11.03.

       Samba commands such as "smbd -V" or "smbstatus"
       will report the underlying base Samba version, for
       example: 2.2.12.

    RESOLUTION:
    The HP-UX CIFS (Samba) version A.01.11.04 is
    available from http://software.hp.com to eliminate
    this vulnerability.

    The HP-UX CIFS (Samba) version A.02.01.01 is
