Synopsis:          Low: tomcat security update for Red Hat Network Satellite Server
Advisory ID:       RHSA-2009:1617-01
Product:           Red Hat Network Satellite Server
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2009-1617.html
Issue date:        2009-11-30

=====================================================================

1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Network Satellite Server 5.1 (RHEL v.4 AS) - noarch

3. Description:

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.

4. Solution:

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