tomcat: denial of service via hash collision

Package(s):tomcat CVE #(s):CVE-2011-4858
Created:January 19, 2012 Updated:February 2, 2012
Description:

From the Novell CVE entry:

Apache Tomcat before 5.5.35, 6.x before 6.0.35, and 7.x before 7.0.23 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.
