Mandriva Linux Security Advisory 2015-052 – Apache Tomcat 7.x before 7.0.47, when an HTTP connector or AJP connector is used, does not properly handle certain inconsistent HTTP request headers, which allows remote attackers to trigger incorrect identification of a request’s length and conduct request-smuggling attacks via a Content-Length header and a Transfer-Encoding: chunked header. Apache Tomcat 7.x before 7.0.50 processes chunked transfer coding without properly handling a large total amount of chunked data or whitespace characters in an HTTP header value within a trailer field, which allows remote attackers to cause a denial of service by streaming data. Various otehr issues have also been addressed.
