tomcat -- multiple vulnerabilities

Apache Software Foundation reports:

Low: Denial of Service CVE-2014-0230
When a response for a request with a request body is
returned to the user agent before the request body is
fully read, by default Tomcat swallows the remaining
request body so that the next request on the connection
may be processed. There was no limit to the size of
request body that Tomcat would swallow. This permitted
a limited Denial of Service as Tomcat would never close
the connection and a processing thread would remain
allocated to the connection.
Moderate: Security Manager bypass CVE-2014-7810
Malicious web applications could use expression
language to bypass the protections of a Security
Manager as expressions were evaluated within a
privileged code section.
