CVE-2011-4084

Summary

Apache Tomcat before 5.5.35, 6.x before 6.0.35, and 7.x before 7.0.23 does not properly handle a large number of form parameters, which might allow remote attackers to cause a denial of service (CPU consumption) via a request that triggers storage of many parameters in a hash table.
