CWE-331  (opens in a new tab)

How to fix?

Upgrade RHEL:10 php to version 0:5.1.6-3.el4s1.10 or higher.
This issue was patched in RHSA-2008:0582.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php package and not the php package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
