The kernel is a vastly bigger program than fetchmail, and it is a highly parallel program, while fetchmail is a sequential program. The kernel must protect one process from interfering with another and enforce privilege; for fetchmail the issues are far simpler. Given this, one would expect to see vastly more security issues in the kernel. For its size, fetchmail has had an unexpectedly large number of security holes. It's not unreasonable to ask why this is so.
