Amazon Linux 2023 : libpq, libpq-devel (ALAS2023-2025-1299)

medium Nessus Plugin ID 277815

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2025-1299 advisory.

Integer wraparound in multiple PostgreSQL libpq client library functions allows an application input provider or network peer to cause libpq to undersize an allocation and write out-of-bounds by hundreds of megabytes. This results in a segmentation fault for the application using libpq. Versions before PostgreSQL 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23 are affected. (CVE-2025-12818)

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 'dnf update libpq --releasever 2023.9.20251208' or or 'dnf update --advisory ALAS2023-2025-1299 --releasever 2023.9.20251208' to update your system.
