The remote host is vulnerable to a Denial of Service (DoS) attack.
The remote host is running PostgreSQL, an open source relational database. This version is vulnerable to multiple flaws where an attacker with local access can cause the service to stop. Successful exploitation would result in the system being unavailable to legitimate users.
Upgrade to version 7.3.16, 7.4.14, 8.0.9, 8.15 or higher.
