CVE-2014-0227 | Ubuntu

java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat 6.x before 6.0.42, 7.x before 7.0.55, and 8.x before 8.0.9 does not properly handle attempts to continue reading data after an error has occurred, which allows remote attackers to conduct HTTP request smuggling attacks or cause a denial of service (resource consumption) by streaming data with malformed chunked transfer coding.

From the Ubuntu Security Team

It was discovered that Tomcat incorrectly handled data with malformed chunked transfer coding. A remote attacker could possibly use this issue to conduct HTTP request smuggling attacks, or cause Tomcat to consume resources, resulting in a denial of service.
