Discussion

PHP 'socket_connect()' Function Stack Buffer Overflow Vulnerability

PHP is prone to a stack-based buffer-overflow vulnerability because the application fails to perform adequate boundary checks on user-supplied input.

An attacker can exploit this issue to execute arbitrary machine code in the context of the PHP process. Failed exploit attempts will likely crash the webserver, denying service to legitimate users.
