Dmitry Vyukov f810d08444 executor: protect against memory corruptions better ... Fuzzer has figured out how to corrupt input/output shmem regions abusing the text memcpy in syz_kvm_setup_cpu. It guessed a negative text_size value that causes the memcpy to overwrite shmem regions. Protect better against such cases: 1. Make text_size unsigned (there is already a check that it is less than 1000). 2. Map input region as readable only, we don't write to it. 3. Add address sanity check to segv_handler, if we see that we are writing into executable data, it's better to crash instantly.		2017-01-25 11:01:30 +01:00
