Summary
Ascii allows out-of-bounds array indexing in safe code
Details

Affected version of this crate had implementation of From<&mut AsciiStr> for &mut [u8] and &mut str. This can result in out-of-bounds array indexing in safe code.

The flaw was corrected in commit 8a6c779 by removing those impls.
