Red Hat Security Advisory 2015-2355-01 - The System Security Services Daemon service provides a set of daemons to manage access to remote directories and authentication mechanisms. It was found that SSSD's Privilege Attribute Certificate responder plug-in would leak a small amount of memory on each authentication request. A remote attacker could potentially use this flaw to exhaust all available memory on the system by making repeated requests to a Kerberized daemon application configured to authenticate using the PAC responder plug-in.
