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

1. Summary:

Updated tomcat6 packages that fix two security issues are now available for
Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Low security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop Optional (v. 6) - noarch
Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch
Red Hat Enterprise Linux Server (v. 6) - noarch
Red Hat Enterprise Linux Server Optional (v. 6) - noarch
Red Hat Enterprise Linux Workstation (v. 6) - noarch
Red Hat Enterprise Linux Workstation Optional (v. 6) - noarch

3. Description:

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

It was found that several application-provided XML files, such as web.xml,
content.xml, *.tld, *.tagx, and *.jspx, resolved external entities,
permitting XML External Entity (XXE) attacks. An attacker able to deploy
malicious applications to Tomcat could use this flaw to circumvent security
restrictions set by the JSM, and gain access to sensitive information on
the system. Note that this flaw only affected deployments in which Tomcat
is running applications from untrusted sources, such as in a shared hosting
environment. (CVE-2013-4590)

It was found that, in certain circumstances, it was possible for a
malicious web application to replace the XML parsers used by Apache Tomcat
to process XSLTs for the default servlet, JSP documents, tag library
descriptors (TLDs), and tag plug-in configuration files. The injected XML
parser(s) could then bypass the limits imposed on XML external entities
and/or gain access to the XML files processed for other web applications
deployed on the same Apache Tomcat instance. (CVE-2014-0119)

All Tomcat users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. Tomcat must be
restarted for this update to take effect.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to use the
Red Hat Network to apply this update are available at
https://access.redhat.com/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

1069911 - CVE-2013-4590 tomcat: information disclosure via XXE when running
untrusted web applications
