## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-xwgj-vpm9-q2rq. This link is maintained to preserve external references. ## Original Description Vulnerable juju introspection abstract UNIX domain socket. An abstract UNIX domain socket responsible for introspection is available without authentication locally to network namespace users. This enables denial of service attacks.

### 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](https://github.com/hyperium/tonic/issues/1897) ### Patches Upgrading to tonic `0.12.3` and above contains the fix. ### Workarounds A custom accept loop is a possible workaround.
