(RHSA-2015:0991) Moderate: tomcat6 security and bug fix update

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.
