apache security update for Stronghold

The Apache Web server contains a security vulnerability which can be used
to launch a denial of service attack, or in some cases, allow remote code
execution.

Versions of the Apache Web server up to and including 1.3.24 contain a bug
in the routines which deal with requests encoded using "chunked" encoding.
A carefully crafted invalid request can cause an Apache child process to
call the memcpy() function in a way that will write past the end of its
buffer, corrupting the stack.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0392 to this issue.

Due to the nature of the overflow on 32-bit Unix platforms, this will most
likely cause a segmentation violation, and the child will terminate.
However, on some 64-bit platforms and some 32-bit platforms it is likely
that it is further exploitable. This could allow arbitrary code to be run
on the server as the user the Apache children are set to run as.

All users of Stronghold are advised to patch or upgrade their servers.

We have backported the security fix from the official Apache 1.3.26
release. The patch and instructions on how to apply it are available
from the Stronghold resource center at http://stronghold.redhat.com/.
