struts security update for Red Hat Application Server

An updated Struts package that fixes several security issues is now
available for Red Hat Application Server.

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

Struts is a framework for building web applications with Java.

A validation bug was found in the way Struts handles
org.apache.struts.taglib.html.Constants.CANCEL requests. If it is possible
for a remote attacker to inject a CANCEL request during a validation
operation, it may be possible for the attacker to acquire credentials
without the proper authentication information. (CVE-2006-1546)

A denial of service bug was found in the way Struts handles
multipart/form-data encoded form data. If it is possible for a remote
attacker to reference the public getMultipartRequestHandler method, the
attacker can prevent the Struts application from functioning properly.
(CVE-2006-1547)

A cross site scripting bug was found in the way Struts displays certain
error messages via its LookupDispatchAction, DispatchAction, and
ActionDispatcher handler. It may be possible for an attacker to construct a
specially crafted URL that could fool a victim into believing they are
viewing a trusted site. (CVE-2006-1548)

All users of Struts should upgrade to this updated package containing
Struts version 1.2.9, which is not vulnerable to these issues.

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.
