Patched tomcat6 updates for Red Hat address vulnerabilities and defects. Critical for secure system functioning.
Updated tomcat6 packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6

Solution

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

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

Summary

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.
It was discovered that the ChunkedInputFilter in Tomcat did not fail subsequent attempts to read input after malformed chunked encoding was detected. A remote attacker could possibly use this flaw to make Tomcat process part of the request body as new request, or cause a denial of service. (CVE-2014-0227)
This update also fixes the following bug:
* Before this update, the tomcat6 init script did not try to kill the tomcat process if an attempt to stop it was unsuccessful, which would prevent tomcat from restarting properly. The init script was modified to correct this issue. (BZ#1207048)
All Tomcat 6 users are advised to upgrade to these updated packages, which correct these issues. Tomcat must be restarted for this update to take effect.
