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 &quot tomcat6&quot init script prevented additional Tomcat instances from starting. As well, running &quot service tomcat6 start&quot caused configuration options applied from &quot /etc/sysconfig/tomcat6&quot to be overwritten with those from &quot /etc/tomcat6/tomcat6.conf&quot . 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.
