MORAL
The moral is obvious. You can't trust code that you did
not totally create yourself. (Especially code from com-
panies that employ people like me.) No amount of
source-level verification or scrutiny will protect you
from using untrusted code. In demonstrating the possi-
bility of this kind of attack, I picked on the C compiler.
I could have picked on any program-handling program
such as an assembler, a loader, or even hardware mi-
crocode. As the level of program gets lower, these bugs
will be harder and harder to detect. A well-installed
microcode bug will be almost impossible to detect.
