Description

The (1) rand and (2) mt_rand functions in PHP 5.2.6 do not produce cryptographically strong random numbers, which allows attackers to leverage exposures in products that rely on these functions for security-relevant functionality, as demonstrated by the password-reset functionality in Joomla! 1.5.x and WordPress before 2.6.2, a different vulnerability than CVE-2008-2107, CVE-2008-2108, and CVE-2008-4102.

Affected products

PHP: through 4.4.8; through 5.2.5; 4.0-beta1, 4.0-beta3, 4.0-rc1, 4.0-rc2, 4.0.0, 4.0.1 (+56)
