Potential unaligned read

Details
Status unsound
Package atty
Version 0.2.14
URL softprops/atty#50
Date 2021-07-04

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;

  • is-terminal
  • std::io::IsTerminal nightly-only experimental

See advisory page for additional details.
