Updated Apache packages fix chunked encoding issue

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 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. On some platforms this can be remotely
exploited -- allowing arbitrary code to be run on the server.

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

We have backported the security fix from the official Apache 1.3.26
release. This should help minimize the impact of upgrading to our errata
packages.

All users of Apache should update to these errata packages to correct this
security issue.

[Update Jun 26 2002]
Updated packages have been added for Red Hat Linux for S/390. Slight
changes to problem description to take into account possibility of exploits
also on 32-bit platforms.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
