What classes of security bugs could possibly arise from Rust's ownership discipline?
What classes of security bugs could possibly arise from Rust's ownership discipline?
Not all security bugs are related to memory. Many are related to improperly written algorithms (most crypto attacks), or improperly designed requirements (TLSv1).
Even Heartbleed was primarily due to a logic bug (trusting tainted data) instead of an outright memory ownership bug.
Does Rust automatically zero out newly allocated memory? Honest question, I don't know the answer.
Nobody is saying that Rust eliminates all security bugs. Just a huge number of the most common ones.

Yes.
This is a problem that will be there equally in all languages
Perhaps less so in languages with a better type system, but that doesn't affect Rust since there aren't any _systems_ languages with a better type system.
Oh, also: If you're implying that Rust's ownership discipline can create security bugs where there were none before, I consider that a real stretch. I'd need to see an actual bug, or at least a bug concept, that Rust's borrowing/ownership rules create before accepting this.
