The ability to check memory references against their associated array/buffer bounds helps programmers to detect programming errors involving address overruns early on and thus avoid many difficult bugs down the line. Because such programming errors have been the targets of remote attacks, i.e., buffer overflow attack, prevention of array bound violation is essential for the security and robustness of application programs that provide service on the Internet.
