Bugzilla:
750521: CVE-2011-4858 tomcat: hash table collisions CPU usage DoS (oCERT-2011-003)

The MITRE CVE dictionary describes this issue as:

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.
