What is RUSTSEC-2023-0126?
RUSTSEC-2023-0126 is a memory corruption vulnerability in im, published on 4 Feb 2023.
Official description
Inserting into an im::OrdSet (for example by collecting an iterator into one) can violate
Rust's aliasing rules: Miri reports a stacked borrows violation in
sized_chunks::Chunk::force_copy(), which is called during insertion, where a shared borrow
is invalidated by a unique borrow before the read through it completes.
This is undefined behavior, reachable from safe code.
