"The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-3018
advisory.

  - pgjdbc is the offical PostgreSQL JDBC Driver. A security hole was found in the jdbc driver for postgresql
    database while doing security research. The system using the postgresql library will be attacked when
    attacker control the jdbc url or properties. pgjdbc instantiates plugin instances based on class names
    provided via `authenticationPluginClassName`, `sslhostnameverifier`, `socketFactory`, `sslfactory`,
    `sslpasswordcallback` connection properties. However, the driver did not verify if the class implements
    the expected interface before instantiating the class. This can lead to code execution loaded via
    arbitrary classes. Users using plugins are advised to upgrade. There are no known workarounds for this
    issue. (CVE-2022-21724)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
