Multiple security issues were found in the Tomcat servlet and JSP engine: CVE-2013-2067 FORM authentication associates the most recent request requiring authentication with the current session. By repeatedly sending a request for an authenticated resource while the victim is completing the login form, an attacker could inject a request that would be executed using the victim's credentials. CVE-2013-2071 A runtime exception in AsyncListener.onComplete() prevents the request from being recycled. This may expose elements of a previous request to a current request. CVE-2013-4286 Reject requests with multiple content-length headers or with a content-length header when chunked encoding is being used. CVE-2013-4322 When processing a request submitted using the chunked transfer encoding, Tomcat ignored but did not limit any extensions that were included. This allows a client to perform a limited denial of service by streaming an unlimited amount of data to the server. CVE-2014-0050 Multipart requests with a malformed Content-Type header could trigger an infinite loop causing a denial of service. For the stable distribution (wheezy), these problems have been fixed in version 7.0.28-4+deb7u1. For the testing distribution (jessie), these problems have been fixed in version 7.0.52-1. For the unstable distribution (sid), these problems have been fixed in version 7.0.52-1. We recommend that you upgrade your tomcat7 packages.
