The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:5567 advisory.
PostgreSQL is an advanced object-relational database management system (DBMS).
The following packages have been upgraded to a later upstream version: postgresql (10.15).
Security Fix(es):
* postgresql: Reconnection can downgrade connection security settings (CVE-2020-25694)
* postgresql: Multiple features escape security restricted operation sandbox (CVE-2020-25695)
* 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.
