Amazon Linux 2 : postgresql (ALASPOSTGRESQL13-2025-011)

medium Nessus Plugin ID 237506

Language:

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 13.21-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2POSTGRESQL13-2025-011 advisory.

 Buffer over-read in PostgreSQL GB18030 encoding validation allows a database input provider to achieve temporary denial of service on platforms where a 1-byte over-read can elicit process termination. This affects the database server and also libpq. Versions before PostgreSQL 17.5, 16.9, 15.13, 14.18, and 13.21 are affected. (CVE-2025-4207)

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 postgresql' to update your system.
