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.

Red Hat Security Advisory 2014-0686-01 - Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages technologies. It was found that a fix for a previous security flaw introduced a regression that could cause a denial of service in Tomcat 7. A remote attacker could use this flaw to consume an excessive amount of CPU on the Tomcat server by sending a specially crafted request to that server. It was found that when Tomcat 7 processed a series of HTTP requests in which at least one request contained either multiple content-length headers, or one content-length header with a chunked transfer-encoding header, Tomcat would incorrectly handle the request. A remote attacker could use this flaw to poison a web cache, perform cross-site scripting attacks, or obtain sensitive information from other requests.

Red Hat Security Advisory 2014-0429-01 - Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages technologies. It was found that when Tomcat processed a series of HTTP requests in which at least one request contained either multiple content-length headers, or one content-length header with a chunked transfer-encoding header, Tomcat would incorrectly handle the request. A remote attacker could use this flaw to poison a web cache, perform cross-site scripting attacks, or obtain sensitive information from other requests. It was discovered that the fix for CVE-2012-3544 did not properly resolve a denial of service flaw in the way Tomcat processed chunk extensions and trailing headers in chunked requests. A remote attacker could use this flaw to send an excessively long request that, when processed by Tomcat, could consume network bandwidth, CPU, and memory on the Tomcat server. Note that chunked transfer encoding is enabled by default.
