CVE-2011-4885

原文の説明

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.

影響を受けるソフトウェア

• PHP = 5.0.2= 5.1.3= 5.2.12= 5.3.4= 5.0.0= 5.2.14 完全一致
