Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Tonic versions >=0.12.2, <0.12.3 are vulnerable to a remote denial of service when using the tonic::transport::Server. A remote attacker can trigger errors during accepting a TCP or TLS stream that were not handled correctly, causing the server's accept loop to exit cleanly. Upgrade to tonic 0.12.3 or later, which contains the fix.
