Description Josh Bressers 2008-05-08 14:38:33 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2008-2107 to the following vulnerability:

The GENERATE_SEED macro in PHP 4.x before 4.4.8 and 5.x before 5.2.5, when running on 3
2-bit systems, performs a multiplication using values that can produce a zero seed in rare circumstances, which allows context-dependent attackers to predict subsequent values of the rand and mt_rand functions and possibly bypass protection mechanisms that rely on an unknown initial seed.
