Summary

Use of uninitialized memory in temporary

Details

Uninit memory is used as a RNG seed in temporary

The following function is used as a way to get entropy from the system, which does operations on and exposes uninit memory, which is UB.

fn random_seed(_: &Path, _: &str) -> [u64; 2] {
    use std::mem::uninitialized as rand;
    unsafe { [rand::<u64>() ^ 0x12345678, rand::<u64>() ^ 0x87654321] }
}

This has been resolved in the 0.6.4 release.

The crate is not intended to be used outside of a testing environment.

For a general purpose crate to create temporary directories, tempfile is an alternative for this crate.
