Synopsis: Important: apache security update
Advisory ID: RHSA-2006:0618-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2006-0618.html
Issue date: 2006-08-08
Updated on: 2006-08-08
Product: Red Hat Enterprise Linux
CVE Names: CVE-2006-3918
- ---------------------------------------------------------------------

1. Summary:

Updated Apache httpd packages that correct a security issue are now
available for Red Hat Enterprise Linux 2.1.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

The Apache HTTP Server is a popular Web server available for free.

A bug was found in Apache where an invalid Expect header sent to the server
was returned to the user in an unescaped error message. This could
allow an attacker to perform a cross-site scripting attack if a victim was
tricked into connecting to a site and sending a carefully crafted Expect
header. (CVE-2006-3918)

While a web browser cannot be forced to send an arbitrary Expect header by
a third-party attacker, it was recently discovered that certain versions of
the Flash plugin can manipulate request headers. If users running such
versions can be persuaded to load a web page with a malicious Flash applet,
a cross-site scripting attack against the server may be possible.

Users of Apache should upgrade to these updated packages, which contain a
backported patch to correct this issue.

4. Solution:

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

This update is available via Red Hat Network. 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.
