Description Vincent Danen 2010-03-28 03:41:02 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2010-1128 to
the following vulnerability:

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.
