NVD Description

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

In the standard library in Rust before 1.49.0, String::retain() function has a panic safety problem. It allows creation of a non-UTF-8 Rust string when the provided closure panics. This bug could result in a memory safety violation when other string APIs assume that UTF-8 encoding is used on the same string.
