[HPP]

This question for HP:
When will HP release patch for "Apache Web Server Chunk Handling Vulnerability" or when will you release Apache Apache 1.3.26 and Apache 2.0.39?

Thanks

Just so everyone knows what you are talking about here.

ALERT - APACHE WEB VULNERABILITY

Free Vulnerability Scanning Utility Now Available

Two days ago a vulnerability that affects Apache web server software was announced. The vulnerability is a remote buffer overflow in the section of code that handles chunked-encoding requests. It is possible for attackers to manipulate this vulnerability to execute code against any vulnerable versions of Apache. This includes the Unix and Windows versions.

It should also be noted that since the Apache vulnerability was released, exploit programs that take advantage of the vulnerability have been distributed to the Internet. This makes the chances of attack, and even the possibility a large scale attack such as a worm, much greater.

Due to the fact that Apache is the most deployed web server software on the Internet, detecting and patching this vulnerability is critical for many administrators. eEye has created a free tool that IT administrators can use to scan their networks for vulnerable Apache servers. The tool also provides a link to information on how to correctly patch vulnerable servers.

Note: A recent update to eEye's Retina Network Security Scanner included an audit for this particular Apache vulnerability. Retina users should be sure to run an "Auto-Update" to obtain this and other new vulnerability checks.

configure stage)

This article states, that with regards to HP, "...Patches are in process and will be announced in an HP Security Bulletin when available."

Has anyone heard anything relating to HPUX 11.xx??

This was released by HP within the last week.



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).

------------------------------------------------------------------
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.

B. Fixing the problem
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.

System: hprc.external.hp.com

FTP Access: ftp://apache:apache@hprc.external.hp.com/
or: ftp://apache:apache@192.170.19.51/

Retrieve the binaries and verify the correct size, cksum output
and MD5 fingerprint.

As a note there were two revisions made to the security bulletin:

CHANGE SUMMARY: Rev.01 - Do not install the bundle on NNM.
Rev.02 - Added Virtualvault patches.

Hi,

You are using the gcc compiler.

I had the similar problem and got it resolved using ansic C compiler.

if you have anci C compiler then try the following before
running configure

# export CC=/opt/ansic/bin/cc

# ./configure --prefix=/opt/apache

I am sure it will work.
