CWE-20  (opens in a new tab)

How to fix?

Upgrade RHEL:6 php-tidy to version 0:5.3.3-3.el6_2.5 or higher.
This issue was patched in RHSA-2012:0019.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php-tidy package and not the php-tidy package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

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.
