- Summary
- os_str_bytes relies on undefined behavior of `char::from_u32_unchecked`
- Details
-
The Windows implementation of this crate relied on the behavior of std::char::fromu32unchecked when its safety clause is violated. Even though this worked with Rust versions up to 1.42 (at least), that behavior could change with any new Rust version, possibly leading a security issue.
The flaw was corrected in version 2.0.0.
