RESOLUTION
HP has made the following software updates available to resolve the issue.
Software updates for the Apache-based Web Server are available from:
http://h20293.www2.hp.com/cgi-bin/swdepot_parser.cgi/cgi/displayProductInfo.pl?productNumber=HPUXWSSUITE
HP-UX B.11.00, B.11.11 and HP-UX B.11.23 require the Apache-based Web Server
v.2.0.58.01 or subsequent.
Apache Update Procedure
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 revisions of the product may
co-exist on a single system.
For example, the results of the command swlist -l product | grep -I apache
hpuxwsAPACHE B.2.0.55.00 HP-UX Apache-based Web Server
Stop Apache
-------------
Before updating, make sure the previous Apache binary is stopped. If Apache is
not stopped, the installation would be successful but the new version would be
prevented from starting until a later time.
After determining which Apache is installed, stop Apache with the following
commands:
for hpuxwsAPACHE: /opt/hpws/apache[32]/bin/apachectl stop
Download and Install Apache
--------------------------
Download Apache from Software Depot.
http://h20293.www2.hp.com/cgi-bin/swdepot_parser.cgi/cgi/displayProductInfo.pl?productNumber=HPUXWSSUITE
Verify successful download by comparing the cksum with the value specified on
the installation web page.
Use SD to swinstall the depot. Installation of this new revision of HP Apache
over an existing HP Apache installation is supported, while installation over a
non-HP Apache is NOT supported.
Removing Apache Installation
---------------------------
The potential vulnerability can also be resolved by removing Apache rather than
installing a newer revision. To remove Apache use both Software Distributor's
"swremove" command and also "rm -rf" the home location as specified in the
rc.config.d file "HOME" variables.
%ls /etc/rc.config.d | \ grep apache hpapache2conf hpws_apache[32]conf
MANUAL ACTIONS: Yes - Update plus other actions
Install the revision of the product.
