    CVE-2020-36317

    Published: 11 Apr 2021Last Modified: 9 Jul 2026

    Summary:

    Details: 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.
