RUSTSEC-2024-0001: 
Rust vulnerability analysis and mitigation

Affected versions receive a &[u8] from the caller through a safe API, and pass it directly to the unsafe str::from_utf8_unchecked function. The behavior of ferris_says::say is undefined if the bytes from the caller don't happen to be valid UTF-8. The flaw was corrected in [ferris-says#21] by using the safe str::from_utf8 instead, and returning an error on invalid input. However this fix has not yet been published to crates.io as a patch version for 0.2. Separately, [ferris-says#32] has introduced a different API for version 0.3 which accepts input as &str rather than &[u8], so is unaffected by this bug.
