CVE-2023-22466

Tokio is a runtime for writing applications with Rust. Starting with
version 1.7.0 and prior to versions 1.18.4, 1.20.3, and 1.23.1, 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. Remote clients may only access the named pipe if the named
pipe’s associated path is accessible via a publicly shared folder (SMB).
Versions 1.23.1, 1.20.3, and 1.18.4 have been patched. 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. As a workaround, ensure that pipe_mode is set first after
initializing a ServerOptions.
