Vulnerability Name:

CVE-2010-1128 (CCN-56536)

Assigned:2010-02-25
Published:2010-02-25
Updated:2010-12-10
Summary:The Linear Congruential Generator (LCG) in PHP before 5.2.13 does not provide the expected entropy, which makes it easier for context-dependent attackers to guess values that were intended to be unpredictable, as demonstrated by session cookies generated by using the uniqid function.
