Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of postgresql installed on the remote host is prior to 13.7-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2POSTGRESQL13-2023-002 advisory.

2024-08-28: CVE-2021-3677 was added to this advisory.

2024-02-29: CVE-2021-23222 was added to this advisory.

A man-in-the-middle attacker can inject false responses to the client's first few queries, despite the use of SSL certificate verification and encryption. (CVE-2021-23222)

A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting. (CVE-2021-3677)

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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update postgresql' to update your system.
