SECURITY BULLETIN: HPSBUX0304-254
Originally issued: 09 April 2003
Last revised: 30 April 2003
SSRT3536 Potential Security Vulnerability in CIFS/9000 Server
(rev.2)
-----------------------------------------------------------------
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
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.
MANUAL ACTIONS: Yes - Update
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.
Rev.02 - clarify version identification
-----------------------------------------------------------------
A. Background
Note: Although having similar descriptions, this is a
different vulnerability from that described in
HPSBUX0303-251:
SSRT3509 Potential Security Vulnerability
in CIFS/9000 Server
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.
**REVISED 02**
-->Note: The HP CIFS Server versions do not map directly to
--> original Samba versions. Significant Samba fixes,
--> including security fixes, are backported into the
--> HP CIFS Server. Specific security-related code was
--> backported from 2.2.8a into the current HP CIFS Server
--> source, which is based on Samba 2.2.5. The what(1)
--> output will show the HP version string, for example:
--> A.01.09.04. Samba commands such as "smd -V" or
--> smbstatus will only report the underlying base Samba
--> version, for example: 2.2.5.
B. Recommended solution
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.

bulletin has been implemented on HP-UX 11.XX systems providing
that the fix is completely implemented in a patch with no
manual actions required. The Security Patch Check tool cannot
verify fixes implemented via a product upgrade.
