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

The information in the following Security Bulletin should be
acted upon as soon as possible.  Hewlett-Packard Company will
not be liable for any consequences to any customer resulting
from customer's failure to fully implement instructions in this
Security Bulletin as soon as possible.

PROBLEM: CIFS/9000 Server is potentially vulnerable to altered
         SMB/CIFS network messages.

IMPACT: Potential remote root access.

PLATFORM: All HP9000 servers running CIFS/9000 Server versions up
          through A.01.09.02 on HP-UX 11.0, 11.11(11i), and 11.22

**REVISED 01**
SOLUTION: HP-UX 11.0, 11.11, 11.22
 -->      Download and install the CIFS Server 2.2e version
 -->      A.01.09.04 or subsequent from software.hp.com.


 -->            HP-UX 11.0, 11.11, 11.22
 -->            Download and install the CIFS Server 2.2e version
 -->            A.01.09.04 or subsequent from software.hp.com.

AVAILABILITY:  CIFS Server 2.2e version A.01.09.04 is available
               now from software.hp.com.

CHANGE SUMMARY: Rev.01 - CIFS Server 2.2e version A.01.09.04
                         available for 11.00, 11.11, 11.22.
 A. Background

    Note:  Although having similar descriptions, this is a
           different vulnerability from that described in
           SSRT3509 Potential Security Vulnerability
                    in CIFS/9000 Server
**REVISED 01**
 -->       CIFS Server 2.2e version A.01.09.04 corrects
 -->       both vulnerabilities.

    Note: The following are not vulnerable:

            HP OpenVMS
            HP NonStop Servers
            HP Secure Web Servers for HP Tru64 UNIX
            HP Secure Web Servers for HP Tru64 OpenVMS

          As further information becomes available HP
          will provide notice of the availability of any
          additional Samba updates through standard security
          bulletin announcements and information will be
          available from your normal HP Services support channel.

    CIFS Server version A.01.09.02 and prior may allow modified
    SMB/CIFS messages to cause smbd to overwrite portions of its
    own process address space.  This could potentially be
    exploited to gain root access remotely.

    The latest version of CIFS Server adds checks for proper
    SMB/CIFS messages to prevent invalid smbd memory accesses.

 B. Recommended solution
**REVISED 01**

 -> HP-UX 11.0, 11.11, 11.22

 -> Update to version A.01.09.04 (available on software.hp.com).
 -> This version includes the fixes provided by the binary
 -> replacement files smbd.11.00 (version A.01.09.02) and
 -> smbd.11.00.r1 (A.01.09.03) previously available via FTP
 -> access.
