tomcat: Mishandling of Transfer-Encoding header allows for HTTP request smuggling

A flaw was found in Apache Tomcat. The HTTP header parsing code used an approach to end-of-line EOL parsing that allowed some invalid HTTP headers to be parsed as valid. This led to the possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the...
