Amazon Linux 2 : libpq (ALASPOSTGRESQL12-2024-012)

high Nessus Plugin ID 208050

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 12.20-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2POSTGRESQL12-2024-012 advisory.

 Time-of-check Time-of-use (TOCTOU) race condition in pg_dump in PostgreSQL allows an object creator to execute arbitrary SQL functions as the user running pg_dump, which is often a superuser. The attack involves replacing another relation type with a view or foreign table. The attack requires waiting for pg_dump to start, but winning the race condition is trivial if the attacker retains an open transaction.
 Versions before PostgreSQL 16.4, 15.8, 14.13, 13.16, and 12.20 are affected. (CVE-2024-7348)

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

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

Solution

Run 'yum update libpq' to update your system.
