Description Robert Frohl 2021-04-12 07:46:29 UTC 
CVE-2020-36317

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.
