RHEL 10 : postgresql16 (RHSA-2026:0456)

medium Nessus Plugin ID 283564

Synopsis

The remote Red Hat host is missing one or more security updates for postgresql16.

Description

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:0456 advisory.

PostgreSQL is an advanced Object-Relational database management system (DBMS). The base postgresql package contains the client programs that you'll need to access a PostgreSQL DBMS server, as well as HTML documentation for the whole system. These client programs can be located on the same machine as the PostgreSQL server, or on a remote machine that accesses a PostgreSQL server over a network connection.
The PostgreSQL server can be found in the postgresql-server sub-package.

Security Fix(es):

* postgresql: CREATE STATISTICS does not check for schema CREATE privilege (CVE-2025-12817)

* postgresql: libpq undersizes allocations, via integer wraparound (CVE-2025-12818)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL postgresql16 package based on the guidance in RHSA-2026:0456.
