Amazon Linux 2 : libpq (ALASPOSTGRESQL12-2023-003)

high Nessus Plugin ID 181980

Language:

Synopsis

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

Description

The version of libpq installed on the remote host is prior to 12.11-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2POSTGRESQL12-2023-003 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. 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 these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update libpq' to update your system.
