Details

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.

Upgrading to tonic 0.12.3 and above contains the fix.
