                        removed OV SIP from list of affected
                      Note: Several Apache security bulletins
                      are being revised to correct the affected
                      versions specification.

A. Background
    The Common Vulnerabilities and Exposures project
    < has identified multiple potential
    vulnerabilities in the Jakarta-Tomcat servlet engine
    (CAN-2003-0042, CAN-2003-0043, CAN-2003-0044).
    More details are available at:


     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.11.20
      HP-UX B.11.22
      For B9415AA
 -->  action: install revision 3.3.1a or subsequent

 -->  action: remove (migrate to hpuxwsTOMCAT)

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


B. Recommended solution
   The Apache Group has released Tomcat 3.3.1a as the best known
   version that fixes the problems identified in the above
   mentioned issues.

   Check for Tomcat Installation
   To determine if the Tomcat Servlet Engine from HP is installed
   on your system, use Software Distributor's swlist command.
   Since Tomcat is not visible at the "product" level, search for
   Apache.  All versions of products may co-exist on a single

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

     ApacheStrong     HP Apache-based Web Server
                                   with Strong (128bit) Encryption
     HPApache  HP Apache-based Web Server

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

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

     for ApacheStrong:    /opt/tomcat/bin/
     for HPApache:        /opt/hpapache2/tomcat/bin/

   Since Tomcat is bundled with Apache, Apache also needs to be

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

   Download and Install Tomcat and Apache
   - Download Tomcat/Apache from Software Depot:
   - 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 installed, migrate to
     hpuxwsTOMCAT and remove the affected products from the

   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 Tomcat Installation
   If you prefer to remove Tomcat 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

   NOTE:  Apache will also be removed.

   NOTE:  For HP Apache 1.3.x, you must manually remove the Apache
          directory in addition to the Tomcat directory. Apache is
          under directory "/opt/apache" for HP Apache 1.3.x.
