o  Security Bulletin Digest Split
   ------------------------------

   The security bulletins digest has been split into multiple digests
   based on the operating system (HP-UX, MPE/iX, and HP Secure OS 
   Software for Linux).  You will continue to receive all security
   bulletin digests unless you choose to update your subscriptions.  
   
   To update your subscriptions, use your browser to access the
   IT Resource Center on the World Wide Web at:

     http://support.itrc.hp.com/

   Under the Maintenance and Support Menu, click on the "more..." link.
   Then use the 'login' link at the left side of the screen to login
   using your IT Resource Center User ID and Password.

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

   To subscribe or unsubscribe to a specific security bulletin digest, 
   select or unselect the checkbox beside it. Then click the 
   "Update Subscriptions" button at the bottom of the page.

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

 -----------------------------------------------------------------
PROBLEM: 1. mod_cgid mishandling of CGI redirect paths could
            result in CGI output going to the wrong client when a
            threaded MPM is used.

            More details are available at:
      http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0789

         2. A buffer overflow could occur in mod_alias and
            mod_rewrite when a regular expression with more than
            9 captures is configured.

            More details are available at:

 -----------------------------------------------------------------
A. Background
   The Common Vulnerabilities and Exposures project
   <http://cve.mitre.org/> has identified potential
   vulnerabilities in the Apache HTTP Server (CAN-2003-0789, and
   CAN-2003-0542).  It affects the following HP product
   numbers/versions on HP-UX releases B.11.00, B.11.11, B.11.20,
   B.11.22, and B.11.23:

   - hp apache-based web server, 2.0.43.04 or earlier
     (HPApache/B9416AA)

   - hp-ux apache-based web server, v.1.0.09.01 or earlier
     (hpuxwsAPACHE/hpuxwsApache)

   - hp apache-based web server, 2.0.43.04 (with IPv6 support)
     or earlier (HPApache/B9416BA)

   - hp-ux apache-based web server (with IPv6 support),
     v.1.0.09.01 or earlier (hpuxwsAPACHE/hpuxwsApache)

   AFFECTED VERSIONS

   The following is a list of affected filesets or patches
   and fix information. To determine if a system has an
   affected version, search the output of
   "swlist -a revision -l fileset" for an affected fileset
   or patch, then determine if a fixed revision or applicable
   patch is installed.

         HP-UX B.11.00
         HP-UX B.11.11
         HP-UX B.11.20
         HP-UX B.11.22
         HP-UX B.11.23
         ====================================
         HPApache.APACHE2
         hpuxwsAPACHE.APACHE2
         fix: install hp-ux apache-based web server, v.1.0.01.01
              or later.

   END AFFECTED VERSIONS

B. Recommended solution
   The Apache Software Foundation has released Apache 2.0.48 as
   the best known version that fixes the problems identified in
   the above mentioned issues.

   For customers using HPApache/B9416AA HPApache/B9416BA and
   hpuxwsAPACHE/hpuxwsApache, HP has incorporated Apache 2.0.48
   in the following product:
   - hp-ux apache-based web server v.1.0.10.01 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

     HPApache      2.0.39.01.02  HP Apache-based Web Server
     hpuxwsAPACHE  A.1.0.09.01   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/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
        hpapache2conf
        hpws_apacheconf

   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:
