Details

David Jorm discovered that Tomcat incorrectly handled certain requests
submitted using chunked transfer encoding. A remote attacker could use this
flaw to cause the Tomcat server to consume resources, resulting in a denial
of service. (CVE-2014-0075)

It was discovered that Tomcat did not properly restrict XSLT stylesheets.
An attacker could use this issue with a crafted web application to bypass
security-manager restrictions and read arbitrary files. (CVE-2014-0096)

It was discovered that Tomcat incorrectly handled certain Content-Length
headers. A remote attacker could use this flaw in configurations where
Tomcat is behind a reverse proxy to perform HTTP request smuggling attacks.
(CVE-2014-0099)
