Description

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

The Red Hat Security Response Team has rated this update as having important 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.

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

A denial of service flaw was found in the way certain strings were converted to Double objects. A remote attacker could use this flaw to cause Tomcat to hang via a specially crafted HTTP request. (CVE-2010-4476)

A flaw was found in the Tomcat NIO (Non-Blocking I/O) connector. A remote attacker could use this flaw to cause a denial of service (out-of-memory condition) via a specially crafted request containing a large NIO buffer size request value. (CVE-2011-0534)

This update also fixes the following bug :

  • A bug in the

This update also fixes the following bug :

* A bug in the 'tomcat6' init script prevented additional Tomcat
instances from starting. As well, running 'service tomcat6 start'
caused configuration options applied from '/etc/sysconfig/tomcat6' to
be overwritten with those from '/etc/tomcat6/tomcat6.conf'. With this
update, multiple instances of Tomcat run as expected. (BZ#676922)

Users of Tomcat should upgrade to these updated packages, which
contain backported patches to correct these issues. Tomcat must be
restarted for this update to take effect."
