Solution

Summary

OpenStack Swift () is a highly available, distributed, eventually consistent object/blob store.
An XML injection flaw in OpenStack Swift could allow remote attackersto manipulate the contents of XML responses via specially-crafted data. This could be used to trigger a denial of service. (CVE-2013-2161)
Red Hat would like to thank Alex Gaynor from Rackspace for reporting this issue.
This update also fixes the following bug:
* If permissions on the "/etc/swift/" directory were incorrect, services (such as swift-proxy-server) flooded the console and "/var/log/messages" with "UNCAUGHT EXCEPTION" errors, including a traceback and "Permission denied: '/etc/swift/proxy-server.conf'" message. This could occur when restarting a service or updating the packages. (BZ#967631)
All users of openstack-swift are advised to upgrade to these updated packages, which correct these issues. After installing this update, the OpenStack Swift services will be restarted automatically.
