Description

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.

Affected products and versions

  • PHP — Up to and including 4.4.7
  • PHP versions 5, 5.0.0beta1, 5.0.0beta2, 5.0.0beta3, 5.0.0rc1, 5.0.0rc2, 5.0.0rc3, 5.0.1, 5.0.2, 5.0.3, 5.0.4, 5.0.5, 5.1.0, 5.1.1, 5.1.2, 5.1.3, 5.1.4, 5.1.5, 5.1.6, 5.2.0, 5.2.1, 5.2.2, 5.2.3, 5.2.4
