PHP GENERATE_SEED() weak security

php-generateseed-weak-security (42226) The risk level is classified as LowLow Risk

Description:

PHP, when running on 64-bit systems, could provide weaker than expected security. A multiplication process by the GENERATE_SEED macro function creates zero bit portions and makes attacks easier on protection mechanisms that use the rand and mt_rand functions. A remote attacker could exploit this vulnerability to generate predictable random numbers and gain unauthorized access to the applications.
