CBL Mariner 2.0 Security Update: postgresql (CVE-2025-4207)

medium Nessus Plugin ID 241888

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of postgresql installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-4207 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)

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

Solution

Update the affected packages.
