If Keystone was configured to use\nLDAP authentication, and the LDAP server was configured to allow anonymous\nbinds (anonymous binds is a common default), anyone able to connect to a\ngiven service using Keystone could connect as any user, including the\nadmin, without supplying a password. (CVE-2013-2157)\n\nRed Hat would like to thank Thierry Carrez of OpenStack upstream for\nreporting this issue. Upstream acknowledges Jose Castro Leon of CERN as\nthe original reporter.\n\nAll users of openstack-keystone are advised to upgrade to these updated\npackages, which correct this issue. After installing the updated packages,\nthe Keystone service (openstack-keystone) will be restarted automatically.",
