RUSTSEC-2024-0376: console-subscriber can be shut down remotely if tokio_unstable feature is activated and the console server is exposed manually

[github-actions]

Remotely exploitable Denial of Service in Tonic

Details
Package	tonic
Version	0.12.1
URL	GHSA-4jwc-w2hc-78qv
Date	2024-10-01
Patched versions	>=0.12.3

Impact

When using tonic::transport::Server there is a remote DoS attack that can cause the server to exit cleanly on accepting a tcp/tls stream. This can be triggered via causing the accept call to error out with errors there were not covered correctly causing the accept loop to exit.

More information can be found here

Patches

Upgrading to tonic 0.12.3 and above contains the fix.

Workarounds

A custom accept loop is a possible workaround.

See advisory page for additional details.

Looks like very low priority. It's only a dependency of console_subscriber which is disabled by default unless the tokio_unstable is enabled. And even then, it's on a server that isn't expected to run outside of a localhost environment.
