Scientific Linux Security Update : authconfig on SL7.x x86_64

Medium Nessus Plugin ID 102637


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


Security Fix(es) :

- A flaw was found where authconfig could configure sssd in a way that treats existing and non-existing logins differently, leaking information on existence of a user.
An attacker with physical or network access to the machine could enumerate users via a timing attack.


Update the affected authconfig, authconfig-debuginfo and / or authconfig-gtk packages.
