Smashing the heap by overflowing the stack
- rurban 11y agoNot only -fstack-check protects from this exploit, also the new clang -fcpi checker in levee https://github.com/cpi-llvm https://github.com/cpi-llvm and of course the old -fsanitize=address. -fcps does not catch it. I haven't checked -fsanitize=safe-stack yet, as my old levee build didn't offer that.
- rurban 11y agoBuild it now: clang-3.7 -fsanitize=safe-stack does not catch it, and the clang and gcc optimizers with -O optimize it away.
