## Description

Apache Tomcat 5.5.0 through 5.5.29, 6.0.0 through 6.0.27, and 7.0.0 beta
does not properly handle an invalid Transfer-Encoding header, which allows
remote attackers to cause a denial of service (application outage) or
obtain sensitive information via a crafted header that interferes with
"recycling of a buffer."
