                      versions specification.

**REVISED 03**
A. Background


      The following is a list by HP-UX revision 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.

      For IPv4:
      HP-UX B.11.00
      HP-UX B.11.11
      HP-UX B.11.22
 -->  action: revision A. or subsequent

      For IPv6:
      HP-UX B.11.11
 -->  action: install revision B. or subsequent

      HP-UX B.11.23
 -->  action: install revision B. or subsequent

      HP-UX B.11.04 VirtualVault 4.5
 -->  action: install PHSS_29892, PHSS_29690 or subsequent

      HP-UX B.11.04 VirtualVault 4.6
 -->  action: install PHSS_29893, PHSS_29691, PHSS_29891
           or subsequent.

      HP-UX B.11.04 Virtualvault 4.7
 -->  action: install PHSS_30055, PHSS_30056, PHSS_30057
           or subsequent.

      HP-UX B.11.04 Webproxy 2.0
 -->  action: install PHSS_29894 or subsequent

      HP-UX B.11.04 Webproxy 2.1
 -->  action: install  PHSS_30058 or subsequent


     NOTE: HP-UX B.11.04 does not support IPv6.

B. Recommended solution

   HP has incorporated OpenSSL 0.9.7b + patches into the
   hpuxwsAPACHE product revisions listed above.

   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     might show:

     hpuxwsAPACHE  A.   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 hpuxwsAPACHE:    /opt/hpws/apache/bin/apachectl stop

   Download and Install Apache
    - Download Apache from < (see above).
    - Use SD to swinstall the depot.

   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 prefer to remove Apache from your system instead of
   installing 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

   For customers with HP-UX release B.11.04 (VVOS), stop Apache
   (as above), and install the patches listed above.
