Summary

atty potential unaligned read

Description

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"
