Description Josh Bressers 2008-05-08 14:40:17 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2008-2108 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 64-bit systems, performs a multiplication that generates a portion of zero bits during conversion due to insufficient precision, which produces 24 bits of entropy and simplifies brute force attacks against protection mechanisms that use the rand and mt_rand functions.
