Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS : PostgreSQL vulnerability (USN-5440-1)

high Nessus Plugin ID 161474

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 21.10 / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5440-1 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.

Solution

Update the affected packages.
