The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2728 advisory.

    PostgreSQL is an advanced object-relational database management system (DBMS).

    The following packages have been upgraded to a later upstream version: postgresql (9.2.23). (BZ#1484639,     BZ#1484647)

    Security Fix(es):

    * It was found that authenticating to a PostgreSQL database account with an empty password was possible     despite libpq's refusal to send an empty password. A remote attacker could potentially use this flaw to     gain access to database accounts with empty passwords. (CVE-2017-7546)

    * An authorization flaw was found in the way PostgreSQL handled access to the pg_user_mappings view on     foreign servers. A remote, authenticated attacker could potentially use this flaw to retrieve passwords     from the user mappings defined by the foreign server owners without actually having the privileges to do     so. (CVE-2017-7547)

    Red Hat would like to thank the PostgreSQL project for reporting these issues. Upstream acknowledges Ben     de Graaff, Jelte Fennema, and Jeroen van der Ham as the original reporters of CVE-2017-7546; and Jeff     Janes as the original reporter of CVE-2017-7547.

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.
