CVE-2020-36317 (GCVE-0-2020-36317)

Vulnerability from cvelistv5 – Published: 2021-04-11 19:06 – Updated: 2024-08-04 17:23

Summary

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.

Severity

No CVSS data available.
