apache security update for Stronghold

An updated version of Apache that addresses several security issues is now
available for Stronghold 4.0 for Enterprise Linux.

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

The Apache HTTP server is a powerful, full-featured, efficient, and
freely-available Web server.

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.

A flaw in mod_imap when using the Referer directive with image maps was
discovered. With certain site configurations, a remote attacker could
perform a cross-site scripting attack if a victim can be forced to visit a
malicious URL using certain web browsers. (CVE-2005-3352)

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

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.
