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:

         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:

         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

         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

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).


AVAILABILITY: Complete product bundles are available from the
              ftp site (see below), not on
              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

    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


     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
    HP WBEM Services, A.01.05.05 or earlier
    action: install revision A.01.05.07 or subsequent


    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:
 -> /

    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
 ->- Download the depot for HP WBEM Services for HP-UX from
     the URL above.
   - To update to the new version, login as root and use the
     swinstall command to install the product:
     swinstall -s <depotname>

   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.
