A. Background
   The Common Vulnerabilities and Exposures project (
   has identified multiple potential vulnerabilities in the Apache
   HTTP Server.  It affects the following HP product numbers:

     B9415AA Apache 1.3.x  HP-UX releases 11.00 and 11.11
     B9416AA Apache 2.x    HP-UX releases 11.00 and 11.11
     B9415AA Apache 1.3.x  HP-UX releases 11.20 and 11.22
     B9416AA Apache 2.x    HP-UX releases 11.20 and 11.22
     B9416BA Apache 2.x    IPv6 HP-UX release 11.11
  -->B5411EA Virtualvault 4.5 (VVOS 11.04)
  -->B5411FA Virtualvault 4.6 (VVOS 11.04)

   With this release HP has upgraded to Apache 2.0.43 and
   Apache 1.3.27, and fixes certain known potential vulnerabilities
   in the Apache HTTP Server.
   The release incorporates fix for the following problems:
     CAN-2002-0839 : Apache 1.3.26
     CAN-2002-0840 : Apache 1.3.26 and Apache 2.0.39
     CAN-2002-0843 : Apache 1.3.26 and Apache 2.0.39
     CAN-2002-1156 : Apache 2.0.39
   More details on this information can be found at
   The CVE issues can be found at

   The Apache Group has released Apache 2.0.43 and Apache
   1.3.27 as the best known version that fixes the problems
   identified in the above mentioned CVE issues.

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

    The command to stop the HP Apache binary is:
        for 1.3.26:
            /opt/apache/bin/apachectl stop
        for 2.0.39:
            /opt/hpapache2/bin/apachectl stop

    HP Apache automatically starts upon installation if port 80
    is available.

    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.

**REVISED 01**

    The fixes for all HP-UX versions are in the form of new product
    bundles, instead of patches.  To retrieve them, go to
