Overview
smallvec is a "Small vector" optimization for Rust: store up to a small number of items on the stack.
Affected versions of this package are vulnerable to Buffer Overflow in SmallVec::insert_many. Exploiting this vulnerability is possible only if the iterator passed to insert_many yielded more items than the lower bound returned from its size_hint method.
