Memory Corruptions #208

Open elManto opened 3 years ago

poc.tar.gz

I found some memory corruptions while fuzzing c2m for research purposes. They mostly are heap BOFs, and SEGV. To reproduce you just need to compile mir with ASAN enabled and feed ``c2mir'' with one of the POCs which are present in the tar gz I attached.

I did a bit of triage, but there could be some duplicates.

Thank you very much for the fuzzing tests. I'll work on fixing the crashes.
