The remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5676-1 advisory.

  • A flaw was found in PostgreSQL. There is an issue with incomplete efforts to operate safely when a privileged user is maintaining another user’s objects. The Autovacuum, REINDEX, CREATE INDEX, REFRESH MATERIALIZED VIEW, CLUSTER, and pg_amcheck commands activated relevant protections too late or not at all during the process. This flaw allows an attacker with permission to create non-temporary objects in at least one schema to execute arbitrary SQL functions under a superuser identity. (CVE-2022-1552)

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