CVE-2014-0075 Denial of Service
Vendor: The Apache Software Foundation
Versions Affected: - Apache Tomcat 8.0.0-RC1 to 8.0.3 - Apache Tomcat 7.0.0 to 7.0.52 - Apache Tomcat 6.0.0 to 6.0.39
Description: It was possible to craft a malformed chunk size as part of a chucked request that enabled an unlimited amount of data to be streamed to the server, bypassing the various size limits enforced on a request. This enabled a denial of service attack.
Mitigation: Users of affected versions should apply one of the following mitigations - Upgrade to Apache Tomcat 8.0.5 or later (8.0.4 contains the fix but was not released) - Upgrade to Apache Tomcat 7.0.53 or later - Upgrade to Apache Tomcat 6.0.41 or later (6.0.40 contains the fix but was not released)
Credit: This issue was reported to the Tomcat security team by David Jorm of the Red Hat Security Response Team.
