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

        as possible.

 -----------------------------------------------------------------
PROBLEM: 1. Apache 2.0.40 through 2.0.45 do not properly handle
            threads correctly, potentially allowing a remote
            denial of service.

       More details are available at:
  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0189

         2. A defect in Apache 2.0.37 through 2.0.45 potentially
            allows a remote denial of service.

       More details are available at:
       http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0245

IMPACT: Potential remote Denial of Service

PLATFORM: HP-UX releases B.11.00, B.11.11 and B.11.22 with
          versions of the following products are affected:

         - HPApache/B9416AA and HPApache/B9416BA (all versions)

         - hp-ux apache-based web server, (product hpuxwsAPACHE or
           hpuxwsApache) v.1.0.05.01 or earlier
           This product includes Apache 2.0.45.

        - hp apache-based web server, 2.0.43.04 or earlier
          (HPApache/B9416AA, HPApache/B9416BA)
          This product includes Apache 2.0.43.

        - hp-ux apache-based web server, v.1.0.05.01 or earlier
          (hpuxwsAPACHE/hpuxwsApache)
          This product includes Apache 2.0.45.

AFFECTED FILESETS:
  The affected filesets are: (product.fileset)
  HPApache.APACHE2       2.0.39.01.02   HP Apache 2.0.39
  hpuxwsAPACHE.APACHE2   A.1.0.05.01    2.0.45 base (IPF Binaries)

SOLUTION: For HP-UX releases B.11.00, B.11.11 and B.11.22:
          1. Remove HPApache/B9416AA and HPApache/B9416BA if they
             are installed.

          2. Download and install:
             hp-ux apache-based web server, v.1.0.06.01 or later
             (product hpuxwsAPACHE or bundle hpuxwsApache)

     NOTE: The product install location and structure has changed
           between HPApache/B9416*A and hpuxwsAPACHE/hpuxwsApache.

             This product includes Apache 2.0.46 and is available
             from:
         http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/
             cgi/displayProductInfo.pl?productNumber=HPUXWSSUITE

  NOTE: No IPv6 solution is available at this time.  This Security
        Bulletin will be updated when such becomes available.

MANUAL ACTIONS: Yes - Update
                Install the product containing the fix.
                For customers with HPApache/B9416AA or
                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
               <http://www.software.hp.com/>

 -----------------------------------------------------------------
A. Background
   The Common Vulnerabilities and Exposures project
  <http://cve.mitre.org/> has identified potential vulnerabilities
   in the Apache HTTP Server (CAN-2003-0189, CAN-2003-0245). These
   affect the following HP products on HP-UX releases B.11.00,
   B.11.11 and B.11.22:

    - HPApache/B9416AA and HPApache/B9416BA (all versions)

    - hp-ux apache-based web server products hpuxwsAPACHE and
      hpuxwsApache, v.1.0.05.01 or earlier.

    Note: The following are not vulnerable:
          HP OpenVMS
          HP NonStop Servers
          HP Tru64 UNIX
          HP Tru64 OpenVMS

B. Recommended solution
   The Apache Software Foundation has released Apache 2.0.46 as
   the best known version fixing the potential vulnerabilities
   mentioned above.

   HP has incorporated Apache 2.0.46 in the following product:

    - hp-ux apache-based web server v.1.0.06.01 or later,
      available from:
      http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/
             displayProductInfo.pl?productNumber=HPUXWSSUITE

   NOTE: No IPv6 solution is available at this time. This Security
         Bulletin will be updated when such becomes available.

   Check for Apache Installation
   -----------------------------
   To determine if the Apache web server from HP is installed on
   your system, use Software Distributor's swlist command.  More
   than one version may be present on a single system.

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

     HPApache      2.0.39.01.02  HP Apache-based Web Server
     hpuxwsAPACHE  A.1.0.05.01   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 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, whereas installation over
   a non-HP Apache is NOT supported.

   Removing Apache Installation
   ----------------------------
   If you prefer to remove Apache from your system rather 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
        hpapache2conf
        hpws_apacheconf

   gain access to many areas of the ITRC.  Remember to save the
   User ID assigned to you, and your password.

   In the left most frame select "Maintenance and Support".

   Under the "Notifications" section (near the bottom of
   the page), select "Support Information Digests".

   To -subscribe- to future HP Security Bulletins or other
   Technical Digests, click the check box (in the left column)
   for the appropriate digest and then click the "Update
   Subscriptions" button at the bottom of the page.

   or

   To -review- bulletins already released, select the link

   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
