"An updated tomcat package that fixes several security issues is now
available for Red Hat Network Satellite Server 5.1.

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

Apache Tomcat is a servlet container for the Java Servlet and
JavaServer Pages (JSP) technologies.

This update corrects several security vulnerabilities in the Tomcat
component shipped as part of Red Hat Network Satellite Server. In a
typical operating environment, Tomcat is not exposed to users of
Satellite Server in a vulnerable manner: By default, only Satellite
Server applications are running on Tomcat. This update will reduce
risk in unique Satellite Server environments.

It was discovered that request dispatchers did not properly normalize
user requests that have trailing query strings, allowing remote
attackers to send specially crafted requests that would cause an
information leak. (CVE-2008-5515)

A flaw was found in the way the Tomcat AJP (Apache JServ Protocol)
connector processes AJP connections. An attacker could use this flaw
to send specially crafted requests that would cause a temporary denial
of service. (CVE-2009-0033)

It was discovered that web applications containing their own XML
parsers could replace the XML parser Tomcat uses to parse
configuration files. A malicious web application running on a Tomcat
instance could read or, potentially, modify the configuration and
XML-based data of other web applications deployed on the same Tomcat
instance. (CVE-2009-0783)

Users of Red Hat Network Satellite Server 5.1 are advised to upgrade
to this updated tomcat package, which contains backported patches to
resolve these issues. Tomcat must be restarted for this update to take
effect."
