CHANGE SUMMARY: Rev.1 - added affected versions
                      Note: Several Apache security bulletins
                      are being revised to correct the affected
                      versions specification.

A. Background
   The Common Vulnerabilities and Exposures project
   < has identified potential
   vulnerabilities in the Webmin GUI Administration tool.

   More details are available at:

**REVISED 01**

     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
 -->  action: install revision or subsequent

 -->  action: remove (migrate to hpuxwsWEBMIN)

      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 Webmin Group has released Webmin 1.070 as the best known
   version that fixes the problems identified in the above
   mentioned issues.

   Check for Webmin Installation
   To determine if the Webmin GUI Administration Tool from HP
   is installed on your system, use Software Distributor's swlist
   command. Since Webmin is not visible at the "product" level
   for products prior to hpuxwsWEBMIN, search for Apache as well.
   All versions of products may co-exist on a single system.

   For example, the results of the commands:
   swlist -l product | grep -i webmin
     hpuxwsWEBMIN          A.    HP-UX Webmin-based Admin

   swlist -l product | grep -i apache

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

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

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

     for ApacheStrong:   /opt/apache/webmin/webmin-init stop
     for HPApache:       /opt/hpapache2/webmin/webmin-init stop
     for hpuxwsWEBMIN:   /opt/hpws/webmin/webmin-init stop

   Since Webmin is bundled with Apache for products prior to
   hpuxwsWEBMIN, Apache also needs to be stopped.

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

   Download and Install Webmin/Apache
   - Download Webmin/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 HPApacheA installed, migrate to
     hpuxwsWEBMIN 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 Webmin Installation
   If you prefer to remove Webmin 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:

   For ApacheStrong and HPApache when removing Webmin, you will
   also remove Apache.
     %ls /etc/rc.config.d | grep apache

     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.

   For hpuxwsWebmin/hpuxwsWebmin:
     %ls /etc/rc.config.d | grep webmin
