CVE-2021-28876

In the standard library in Rust before 1.52.0, the Zip implementation has a panic safety issue. It calls __iteratorgetunchecked() more than once for the same index when the underlying iterator panics (in certain conditions). This bug could lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait.
