"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 '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)

Tomcat must be restarted for this update to take effect."
