Background The Common Vulnerabilities and Exposures project (cve.mitre.org) has identified multiple 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 With this release HP has upgraded to Apache 2.0.43 and Apache 1.3.27, and fixes certain known 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 http://www.apache.org. The CVE issues can be found at http://cve.mitre.org 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. B. Fixing the problem The fixes for all HP-UX versions are in the form of new product bundles, instead of patches. To retrieve them, go to http://www.software.hp.com/ISS_products_list.html Install HP Apache versions 1.3.27.00 or 2.0.43.00 or later.
