Synopsis

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

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:5401 advisory.

The libpq package provides the PostgreSQL client library, which allows client programs to connect to PostgreSQL servers.

The following packages have been upgraded to a later upstream version: libpq (12.5). (BZ#1898228, BZ#1901558)

Security Fix(es):

* postgresql: Reconnection can downgrade connection security settings (CVE-2020-25694)

* postgresql: psql's \gset allows overwriting specially treated variables (CVE-2020-25696)

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 libpq package based on the guidance in RHSA-2020:5401.
