- Summary
- `tokio::io::ReadHalf<T>::unsplit` is Unsound
- Details
-
tokio::io::ReadHalf<T>::unsplitcan violate thePincontractThe soundness issue is described in the tokio/issues#5372
Specific set of conditions needed to trigger an issue (a !Unpin type in ReadHalf) is unusual, combined with the difficulty of making any arbitrary use-after-free exploitable in Rust without doing a lot of careful alignment of data types in the surrounding code.
The
tokiofeatureio-utilis also required to be enabled to trigger this soundness issue.Thanks to zachs18 reporting the issue to Tokio team responsibly and taiki-e and carllerche appropriately responding and fixing the soundness bug.
Tokio before 0.2.0 used
futures0.1 that did not havePin, so it is not affected by this issue. - Database specific
