Description

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
