Scientific Linux Security Update : postgresql on SL7.x x86_64 (20170914)

critical Nessus Plugin ID 103244

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

The following packages have been upgraded to a later upstream version:
postgresql (9.2.23).

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)

Solution

Update the affected packages.
