CVE-2021-28878

In the standard library in Rust before 1.52.0, the Zip implementation calls _iteratorgetunchecked() more than once for the same index (under certain conditions) when nextback() and next() are used together. This bug could lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait.
