概要

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.

NVD の説明

pgx is a PostgreSQL driver and toolkit for Go. 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. The problem is resolved in v4.18.2 and v5.5.4. As a workaround, reject user input large enough to cause a single query or bind message to exceed 4 GB in size.
