-----------------------------------------------------------------
PROBLEM: A remotely exploitable vulnerability in handling of large
data chunks in Apache-based web servers.
PLATFORM: HP9000 Servers running HP-UX release 11.00, and 11.11
with the HP Apache product installed.

code.
SOLUTION: For HP-UX releases 11.00 and 11.11, download new product
bundles from the ftp site below.
MANUAL ACTIONS: Install repaired binary
AVAILABILITY: Complete product bundles are available now for 11.00
and 11.11 are available for PA-RISC architecture
platforms via ftp at hprc.external.hp.com (see
below for account details).
CHANGE SUMMARY:

A. Background
The CERT Advisory CA-2002-17 regarding Apache affects the
following HP product numbers:
B9416AA Apache 2.x PA-RISC HP-UX releases 11.00 and 11.11
B9415AA Apache 1.3.x PA-RISC HP-UX releases 11.00 and 11.11
HP Apache 1.3.26 (PA-RISC)
installs into /opt/apache and /opt/tomcat
disk space: 55-65 MB
documents: /opt/apache/htdocs/doc
HP Apache 2.0.39 (PA-RISC)
installs into /opt/hpapache2
disk space: 80-90 MB

HP Apache installation is supported, while installation over a
non-HP Apache is NOT supported.
An advisory has been issued for HP Compaq systems. Please
