Background The CERT Advisory CA-2002-21 regarding PHP, affects the following HP products: 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 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 have been 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. ================================================================== Case id: SSRT2300 - HP Tru64 UNIX, HP OpenVMS, and Internet Express V5.9 o Secure Web Server for HP OpenVMS and HP Tru64 UNIX are not vulnerable. o Internet Express V5.9 contains PHP 4.1.2 which is not listed as vulnerable to this problem. We also have provided an externally downloadable Secure Web Server 5.9.1 kit (with security fixes to Apache) that also contains PHP 4.1.2. B. Fixing the problem Note: OpenView Network Node Manager (NNM) customers should not install these bundles. The version of Apache delivered with NNM is under investigation. This bulletin will be updated when more information is available. The fixes for all versions are in the form of new product bundles rather than patches. Fixes for the following versions can be downloaded from http://www.software.hp.com/ISS_products_list.html : hp apache-based web server v.1.3.26.03 on hp-ux 11.0 and 11i (pa-risc) hp apache-based web server v.1.3.26.03 on hp-ux 11i version 1.5 and 1.6 (ipf) hp apache-based web server v.2.0.39.03 on hp-ux 11.0 and 11i (pa-risc) hp apache-based web server v.2.0.39.03 on hp-ux 11i (pa-risc) for ipv6 hp apache-based web server v.2.0.39.03 on hp-ux 11i version 1.5 and 1.6 (ipf) C.
