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: Potential vulnerability regarding ssl3_get_record in
         s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before
         0.9.6i does not perform a MAC computation if an incorrect
         block cipher padding is used, which causes an information
         leak (timing discrepancy) that may make it easier to
         launch cryptographic attacks that rely on distinguishing
         between padding and MAC verification errors, possibly
         leading to extraction of the original plaintext, aka the
         "Vaudenay timing attack."

      More details are available at:
  <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0078>

IMPACT: Potential information leak.

PLATFORM: HP9000 Servers running HP-UX release 11.00, 11.11,
          11.20, and 11.22 with versions of the following products
          are affected, and represented as:
               product-name, version (product-tag/bundle-tag)

        - hp apache-based web server, 1.3.27.00 or earlier
          (ApacheStrong/B9415AA)
          This product includes OpenSSL 0.9.6g.

                HPApache/B9416BA installed, the fix requires
                migration to hpuxwsAPACHE/hpuxwsApache and
                removing the affected products from the system.

AVAILABILITY: Complete product bundles are available now on

CHANGE SUMMARY: Rev.01 added IPv6 information

 -----------------------------------------------------------------
A. Background
   The Common Vulnerabilities and Exposures project
   <http://cve.mitre.org/> has identified multiple potential
   vulnerabilities in the OpenSSL (CAN-2003-0078). It affects the
   following HP product numbers/versions on HP-UX releases 11.00,
   11.11, 11.20 and 11.22:

   - hp apache-based web server, 1.3.27.00 or earlier
     (ApacheStrong/B9415AA)

   - hp apache-based web server, 2.0.43.00 or earlier
     (HPApache/B9416AA, HPApache/B9416BA)

   - hp-ux apache-based web server, v.1.0.00.01 or earlier
     (hpuxwsAPACHE/hpuxwsApache)

B. Recommended solution
   The OpenSSL Group has released OpenSSL 0.9.6i as the best known
   version that fixes the problems identified in the above
   mentioned issues.

   For customers using ApacheStrong/B9415AA, HP has incorporated
   OpenSSL 0.9.6i in the following product:
   - hp apache-based web server 1.3.27.01 or later
     <http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/
            displayProductInfo.pl?productNumber=B9415AA132701>

   For customers using HPApache/B9416AA, HPApache/B9416BA and
   hpuxwsAPACHE/hpuxwsApache, HP has incorporated OpenSSL 0.9.6i
   in the following product:
   - hp-ux apache-based web server v.1.0.01.01 or later
     <http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/
             displayProductInfo.pl?productNumber=HPUXWSSUITE>

   Check for Apache Installation
   -----------------------------
   To determine if the Apache web server from HP is installed on
   your system, use Software Distributor's swlist command.  All
   three versions products may co-exist on a single system.

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

     ApacheStrong  1.3.19.21     HP Apache-based Web Server
                                   with Strong (128bit) Encryption
     HPApache      2.0.39.01.02  HP Apache-based Web Server
     hpuxwsAPACHE  A.1.0.00.01   HP-UX Apache-based Web Server

   Stop Apache
   -----------------------------
   Before updating, make sure to stop any previous Apache binary.
   Otherwise, the previous binary will continue running,
   preventing the new one from starting, although the installation
   would be successful.

   After determining which Apache is installed, stop Apache with
   the following commands:

     for ApacheStrong:    /opt/apache/bin/apachectl stop
     for HPApache:        /opt/hpapache2/bin/apachectl stop
     for hpuxwsAPACHE:    /opt/hpws/apache/bin/apachectl stop

   Download and Install Apache
   -----------------------------
   - Download Apache from Software Depot using the previously
     mentioned links.
   - Verify successful download by comparing the cksum with the
     value specified on the installation web page.
   - Use SD to swinstall the depot.
   - For customers with HPApache/B9416AA or HPApache/B9416BA
     installed, migrate to hpuxwsAPACHE/hpuxwsApache and
     remove the affected products from the system.

   Installation of this new version of HP Apache over an existing
   HP Apache installation is supported, while installation over a
   non-HP Apache is NOT supported.

   Removing Apache Installation
   ----------------------------
   If you rather remove Apache from your system than install a
   newer version to resolve the security problem, use both
   Software Distributor's "swremove" command and also "rm -rf" the
   home location as specified in the rc.config.d file "HOME"
   variables.

   To find the files containing HOME variables in the
   /etc/rc.config.d directory:

     %ls /etc/rc.config.d | grep apache
        apacheconf
        hpapache2conf
        hpws_apacheconf

   NOTE:  For HP Apache 1.3.x, you must also manually remove the
          Tomcat directory.  Tomcat is under directory
          "/opt/tomcat" for HP Apache 1.3.x.

   to the current Security Patch Matrix. Updated daily, this
   matrix categorizes security patches by platform/OS release,
   and by bulletin topic.  Security Patch Check completely
   automates the process of reviewing the patch matrix for
   11.XX systems.  Please note that installing the patches
   listed in the Security Patch Matrix will completely
   implement a security bulletin _only_ if the MANUAL ACTIONS
   field specifies "No."

   The Security Patch Check tool can verify that a security
   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.

   For information on the Security Patch Check tool, see:
   <http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/
   displayProductInfo.pl?productNumber=B6834AA>
