CVE-2011-4885: Input Validation

First published: Fri Dec 30 2011(Updated: )

PHP before 5.3.9 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.
