NVD Description

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

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