GHSA-g98v-hv3f-hcfr
atty potential unaligned read
On windows, atty dereferences a potentially unaligned pointer.
In practice however, the pointer won't be unaligned unless a custom global allocator is used.
In particular, the System allocator on windows uses HeapAlloc, which guarantees a large enough alignment.
atty is Unmaintained
A Pull Request with a fix has been provided over a year ago but the maintainer seems to be unreachable.
Last release of atty was almost 3 years ago.
Possible Alternative(s)
The below list has not been vetted in any way and may or may not contain alternatives;
- std::io::IsTerminal - Stable since Rust 1.70.0
- is-terminal - Standalone crate supporting Rust older than 1.70.0"
