Originally issued: 01 July 2002
Last revision: 11 July 2002
-----------------------------------------------------------------
The information in the following Security Bulletin should be acted

liable for any consequences to any customer resulting from customer's
failure to fully implement instructions in this Security Bulletin as
soon as possible.
------------------------------------------------------------------
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, 11.04, and
11.11 with the HP Apache product installed.
DAMAGE: Increased privilege, DoS or execution of arbitrary code.
SOLUTION: For HP-UX releases 11.00 and 11.11, download new product
bundles from the ftp site below.
For only HP-UX release 11.04 (VV-OS): apply patches
PHSS_27361 - for VV 4.6 release,
PHSS_27371 - for VV 4.5 release.
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).
HP-UX 11.04 (VV-OS) patches are available now at
itrc.hp.com
CHANGE SUMMARY: Rev.01 - Do not install the bundle on NNM.
Rev.02 - Added Virtualvault patches.
- --->> Rev.03 - Re-released 1.3.26 bits due to an update
- --->> deficiency and other minor problems.
------------------------------------------------------------------
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
documents: /opt/hpapache2/hp_apache_docs
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.
An advisory has been issued for HP Compaq systems. Please
refer to HP Compaq SSRT2253, which says in part:
CSWS Secure Web Server for HP Tru64 UNIX and HP OpenVMS
"Potential Apache Web Server Chunk Handling Vulnerability"
Patches are available for CSWS for HP Tru64 UNIX at:
http://tru64unix.compaq.com/internet/download.htm#sws_v591
Patches are available for CSWS for HP OpenVMS at:
http://www.openvms.compaq.com/openvms/products/ips/apache/
+csws_patches.html
B. Fixing the problem
Note: OpenView Network Node Manager (NNM) customers should not
install the ftp bundles. The version of Apache delivered
with NNM is under investigation. This bulletin will be
updated when more information is available.
The Virtualvault product (also known as HP-UX 11.04) has
patches for its 4.5 and 4.6 releases. The patch for VV 4.6
updates the outside web server to the Apache 1.3.26 version
from the Apache 1.3.22 version shipped with the VV 4.6
release.
For the VV 4.5 patch, the security fix from the Apache 1.3.26
version was backported to the 1.3.19 version per the Apache
Group's patch for httpd 1.2.0-1.3.22.
Both of these Virtualvault patches are available in
itrc.hp.com.
PHSS_27361 - for VV 4.6 release.
PHSS_27371 - for VV 4.5 release.
The fixes for HP-UX 11.00 and 11.11 are in the form of new
product bundles, instead of patches. An ftp server account has
been created to enable timely downloading of these binaries.
