Request for Help - PHP V3.0.12

Can anyone help me with a possible security problem with version 3.0.12 of PHP. I am led to believe that there is a security issue with this release in that if someone deliberately overflows the system buffer, an executable piece of code can find its way into the server and then be used as a trojan horse to breach the security of the system. Is anyone aware of this problem.? thanks Ian ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
