If you can't even begin to vet the source there is no accounting for the bugs and potential back doors. We don't know what the adversaries intentions might be. While it could be profit driven as is the case with most malware it could also be espionage, spying on dissidents, or something else. Of which there maybe no acting on the bug/backdoor. That would make it significantly more difficult to detect in a closed source application.
After that, the next step would be to get someone to provably audit that open source code. We have seen that open source is no guarantee that the eyeballs are actually there. Even some malicious party could distribute something heinous and just get away with it by saying "relax, it's open source".
