CVE-2020-35865

An issue was discovered in the os_str_bytes crate before 2.0.0 for Rust. It has false expectations about char::from_u32_unchecked behavior.

An issue was discovered in the os_str_bytes crate before 2.0.0 for Rust. It has false expectations about char::from_u32_unchecked behavior.

The Windows implementation of this crate relied on the behavior of `std::char::from_u32_unchecked` 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.
