Integer overflow cannot result in memory safety violations in Rust.

But it can overflow, which will result in a different value that the programmer might expect, which can give an attacker a nice "information leak" or worse. This could be a security bug!

Exactly. Memory safety is a very nice property, but is not complete by itself. This primary emphasis on memory safety was part of a critique of Rust by Andrei Alexandrescu: https://www.quora.com/Which-language-has-the-brightest-futur....

And even wrt memory, Rust (with the standard library) is not free of its own warts, see the OOM situation. See e.g https://news.ycombinator.com/item?id=10545877 for a discussion on this.

Just to be clear: I generally like the ideas of Rust. I just dislike its presentation by some as a magic solution to all kinds of concerns.
