NVD Description

Note: Versions mentioned in the description apply only to the upstream rust-toolset:rhel8/rust-src package and not the rust-toolset:rhel8/rust-src package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In the standard library in Rust before 1.52.0, the Zip implementation has a panic safety issue. It calls __iterator_get_unchecked() 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.
