What is CVE-2021-28878?

A flaw in the Rust Standard Library prior to version 1.52.0 affects the Zip implementation, where the function __iterator_get_unchecked() is called multiple times for the same index under certain usage conditions of next_back() and next(). This oversight violates the safety requirement for the TrustedRandomAccess trait, potentially leading to memory safety issues.
