Scientific Linux Security Update : postgresql on SL7.x x86_64

High Nessus Plugin ID 103244


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


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.

- 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.


Update the affected packages.
