Description

### Impact SQL injection can occur if an attacker can cause a single query or bind message to exceed 4 GB in size. An integer overflow in the calculated message size can cause the one large message to be sent as multiple messages under the attacker's control. ### Patches The problem is resolved in v2.3.3 ### Workarounds Reject user input large enough to cause a single query or bind message to exceed 4 GB in size.
