Task dropped in wrong thread when aborting LocalSet task

CVE-2021-38191 / GHSA-2grh-hm3w-w7hv / RUSTSEC-2021-0072

More information

Details

When aborting a task with JoinHandle::abort, the future is dropped in the
thread calling abort if the task is not currently being executed. This is
incorrect for tasks spawned on a LocalSet.

This can easily result in race conditions as many projects use Rc or RefCell
in their Tokio tasks for better performance.

See tokio#3929 for more details.

Data race when sending and receiving after closing a oneshot channel

CVE-2021-45710 / GHSA-fg7r-2g4j-5cgr / RUSTSEC-2021-0124

More information

Details

If a tokio::sync::oneshot channel is closed (via the
oneshot::Receiver::close method), a data race may occur if the
oneshot::Sender::send method is called while the corresponding
oneshot::Receiver is awaited or calling try_recv.

When these methods are called concurrently on a closed channel, the two halves
of the channel can concurrently access a shared memory location, resulting in a
data race. This has been observed to cause memory corruption.

Note that the race only occurs when both halves of the channel are used
after the Receiver half has called close. Code where close is not used, or where the
Receiver is not awaited and try_recv is not called after calling close,
is not affected.

See tokio#4225 for more details.

tokio::io::ReadHalf<T>::unsplit is Unsound

GHSA-4q83-7cq4-p6wg / RUSTSEC-2023-0005

More information

Details

tokio::io::ReadHalf<T>::unsplit can violate the Pin contract

The 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 tokio feature io-util is 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 futures 0.1 that did not have Pin, so it is not
affected by this issue.
