SSRT3622 rev.1 Potential Security Vulnerabilities in HP WBEM
Services for HP-UX
----------------------------------------------------------------
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.

-----------------------------------------------------------------
PROBLEM: 1. Certain ASN.1 encodings that are rejected as invalid
by the parser can trigger a bug in the deallocation
of the corresponding data structure, corrupting the
stack. This can be used as a denial of service
attack. It is currently unknown whether this can be
exploited to run malicious code. This issue does not
affect OpenSSL 0.9.6.

More details are available at:
http://cve.mitre.org/cgi-bin/cvename...=CAN-2003-0545

2. Unusual ASN.1 tag values can cause an out of bounds
read under certain circumstances, resulting in a
denial of service vulnerability.
More details are available at:
http://cve.mitre.org/cgi-bin/cvename...=CAN-2003-0543
http://cve.mitre.org/cgi-bin/cvename...=CAN-2003-0544

3. A malformed public key in a certificate will crash
the verify code if it is set to ignore public key
decoding errors. Exploitation of an affected
application would result in a denial of service
vulnerability.

4. Due to an error in the SSL/TLS protocol handling,
a server will parse a client certificate when one is
not specifically requested.

IMPACT: Potential Denial of Service

PLATFORM: HP9000 Servers running HP-UX release B.11.00, B.11.11,
and B.11.23 with the following versions are affected:

- HP WBEM Services for HP-UX, A.01.05.05 or earlier
(B8465BA)

SOLUTION: For HP-UX releases B.11.00, B.11.11, and B.11.23
download new HP WBEM Services, A.01.05.07 or
subsequent for the HP-UX product from the ftp site.
(See below for details).

MANUAL ACTIONS: Yes - Update

AVAILABILITY: Complete product bundles are available from the
ftp site (see below), not on itrc.hp.com
This bulletin will be updated when different
delivery mechanisms become available.

CHANGE SUMMARY: Rev.1 Updated URL for downloading latest version.

-----------------------------------------------------------------
A. Background
An SSL/TLS testing suite developed by the NISCC (National
Infrastructure Security Co-Ordination Centre in the UK) has
identified ASN.1 parsing vulnerabilities in OpenSSL.

The Common Vulnerabilities and Exposures project
has identified potential
vulnerabilities which affect HP WBEM Services for HP-UX
(CAN-2003-0543, CAN-2003-0544).

HP WBEM Services for HP-UX (B8465BA)includes the following
filesets.

B8465BA HP WBEM Services for HP-UX
B8465BA.WBEMServies WBEM Services CORE Product
B8465BA.WBEMServices.WBEM-CORE WBEM Services CORE Fileset
for hp 9000 servers
B8465BA.WBEMServices.WBEM-CORE-COM WBEM Services COM Fileset
B8465BA.WBEMServices.WBEM-MAN WBEM Services MAN Fileset
B8465BA.WBEMServices.WBEM-MX WBEM Services MX Fileset

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 update is installed.

HP-UX B.11.00
HP-UX B.11.11
HP-UX B.11.23
=============
WBEMServices.WBEM-CORE
HP WBEM Services, A.01.05.05 or earlier
action: install revision A.01.05.07 or subsequent

END AFFECTED VERSIONS

These products were based on OpenSSL 0.9.6i.

** REVISED01 **
B. Recommended solution
The OpenSSL group has released patches to resolve the
vulnerabilities in OpenSSL 0.9.6k.

For customers using B8465BA, HP has incorporated OpenSSL 0.9.6k
in the following product release:

- HP WBEM Services for HP-UX, A.01.05.07, or subsequent
->- HP WBEM Services for HP-UX, A.02.00.10, or subsequent
-> The latest revision can be retrieved from:
-> http://software.hp.com/portal/swdepot/
displayProductInfo.do?productNumber=B8465BA

==================================================
To resolve the issue:

1. Determine the affected version.
-> 2. Download and verify the md5 checksum from the
Electronic Delivery Receipt.
3. Install the appropriate HP WBEM Services depot.


Check for HP WBEM Services Installation
---------------------------------------
To determine if HP WBEM Services for HP-UX is installed on
your system, use Software Distributor's swlist command.

For example, the results of the command
swlist -l product | grep -i WBEM

WBEMServices A.01.05.07 WBEM Services CORE Product

For full information about system requirements and installing
HP WBEM Services, refer to the HP WBEM Services Version 1.5
Release Notes.

** REVISED01 **
Installation Steps
------------------

Removing HP WBEM Services for HP-UX Installation
------------------------------------------------
Although not recommended, HP WBEM Services can be removed
from your system using the Software Distributor's "swremove"
command. Removing HP WBEM Services can seriously affect
the functionality of dependent products.
