RESOLUTION
HP has made the following patches and 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.2.0.58.00 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 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[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
- ----------------------------
If you prefer to remove Apache from your system instead of installing a newer
revision 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.
%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.
