Security Advisory for the Standard Library

Note that the likelihood of this being an <i>actual</i> security issue is extremely low. Rust just takes memory safety very seriously.

This just looks like it allows to bypass safety checks without marking the code as unsafe. But so do most of the bugs listed in <a href="https:&#x2F;&#x2F;github.com&#x2F;rust-lang&#x2F;rust&#x2F;labels&#x2F;I-unsound%20%F0%9F%92%A5" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rust-lang&#x2F;rust&#x2F;labels&#x2F;I-unsound%20%F0%9F%...</a>? What makes this different that it&#x27;s a security issue now?
