pickle Python module when it was configured to use memcached. A remote
attacker on the same network as memcached could exploit this to execute
arbitrary code. This update adds a new memcache_serialization_support
option to support secure json serialization. For details on this new
option, please see /usr/share/doc/swift-proxy/memcache.conf-sample. This
issue only affected Ubuntu 12.04 LTS. (CVE-2012-4406)

Alex Gaynor discovered that Swift did not safely generate XML. An
attacker could potentially craft an account name to generate arbitrary XML
responses to trigger vulnerabilities in software parsing Swift's XML.
