CVE-2008-2107 - Intervening Refuse


The GENERATE_SEED macro in PHP 4.x before 4.4.8 and 5.x before 5.2.5 when running on 32-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.
