Several vulnerabilities have been discovered in Swift, the Openstack object storage. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2013-2161 Alex Gaynor from Rackspace reported a vulnerability in XML handling within Swift account servers. Account strings were unescaped in xml listings, and an attacker could potentially generate unparsable or arbitrary XML responses which may be used to leverage other vulnerabilities in the calling software. CVE-2013-4155 Peter Portante from Red Hat reported a vulnerability in Swift. By issuing requests with an old X-Timestamp value, an authenticated attacker can fill an object server with superfluous object tombstones, which may significantly slow down subsequent requests to that object server, facilitating a Denial of Service attack against Swift clusters.
