Description Fabio Valentini 2024-10-14 15:48:51 UTC

c.f. https://rustsec.org/advisories/RUSTSEC-2023-0020.html

The last release of the "const-cstr" crate was on 2018-02-10. This is also the last day on which code changes happened in the project's git repo on GitHub. The project is now a read-only archive.

The code has some issues that violate Rust soundness rules and can lead to panics when parsing untrusted data.

The const_str and cstr crates are listed as possible alternatives.

Reproducible: Always

Comment 1 Fabio Valentini 2024-10-14 15:50:00 UTC

Note that recent Rust versions now also support this directly with the `c"C-String literal"` syntax, so there's no need to use third-party crates at all in most cases.
