Joshua Harlow discovered that Nova would allow XML entity processing.
A remote unauthenticated attacker could exploit this using the Nova API to cause a denial of service via resource exhaustion.
(CVE-2013-1664).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
