Impact
When using the ch-go library, under a specific condition when the query includes a large, uncompressed malicious external data, it is possible for an attacker in control of such data to smuggle another query packet into the connection stream.
Patches
If you are using ch-go library, we recommend you to update to at least version 0.65.0.
