Description

Authconfig version 6.2.8 is vulnerable to an Information exposure while using SSSD to authenticate against remote server resulting in the leak of information about existing usernames. 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.
