Description Vasyl Kaigorodov 2015-02-10 11:38:32 EST

When a response for a request with a request body is returned to the user agent before the request body is fully read, by default Tomcat swallows the remaining request body so that the next request on the connection may be processed. There was no limit to the size of request body that Tomcat would swallow. This permitted a limited Denial of Service as Tomcat would never close the connection and a processing thread would remain allocated to the connection.

Comment 7 Jason Shepherd 2015-06-29 00:21:58 EDT

I tested this vulnerability against the version of Tomcat6 shipped with RHEL 6.6 and found it to be unaffected. I'm updating the whiteboard to reflect that.
