Descriptions

Pacemaker 1.1.10, when remote Cluster Information Base (CIB) configuration or resource management is enabled, does not limit the duration of connections to the blocking sockets, which allows remote attackers to cause a denial of service (connection blocking).

Pacemaker 1.1.10, cuando la configuración o recurso de la administración remota Cluster Information Base (CIB) está activada, no limita la duración de las conexiones hacia los sockets de bloqueo, lo que permite a atacantes remotos provocar una denegación de servicio (bloqueo de conexión).

Pacemaker is a high-availability cluster resource manager with a powerful policy engine. A denial of service flaw was found in the way Pacemaker performed authentication and processing of remote connections in certain circumstances. When Pacemaker was configured to allow remote Cluster Information Base configuration or resource management, a remote attacker could use this flaw to cause Pacemaker to block indefinitely. Note: The default Pacemaker configuration in Red Hat Enterprise Linux 6 has the remote CIB management functionality disabled.
