GitHub Vulnerability Alerts

CVE-2023-22466

Impact

When configuring a Windows named pipe server, setting pipe_mode will reset reject_remote_clients to false. If the application has previously configured reject_remote_clients to true, this effectively undoes the configuration. This also applies if reject_remote_clients is not explicitly set as this is the default configuration and is cleared by calling pipe_mode.

Remote clients may only access the named pipe if the named pipe's associated path is accessible via a publically shared folder (SMB).

Patches

The following versions have been patched:

• 1.23.1
• 1.20.3
• 1.18.4

The fix will also be present in all releases starting from version 1.24.0.

Named pipes were introduced to Tokio in version 1.7.0, so releases older than 1.7.0 are not affected.

Workarounds

Ensure that pipe_mode is set first after initializing a ServerOptions. For example:

let mut opts = ServerOptions::new();
opts.pipe_mode(PipeMode::Message);
opts.reject_remote_clients(true);

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.
