Brave New 64-Bit World

Memory requirements on server and desktop systems have risen considerably over the past few years, to the point where 32-bit architectures are not capable of addressing the required amount of memory. A variety of 64-bit CPUs and operating systems have been introduced to resolve this architecture imposed limitation and these are now being widely adopted.

However, any porting of software to 64-bit compatibility can have unexpected security implications. This paper discusses some of these implications and how to resolve them.
