CVE-2008-2108 (GCVE-0-2008-2108)

Vulnerability from cvelistv5 – Published: 2008-05-07 21:00 – Updated: 2024-08-07 08:49
VLAI
Summary
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.
Severity
