CVE-2013-2256 medium priority: Ubuntu including 1 source packages (nova), 6 status rows across 6 suites (lucid, precise, quantal, raring, saucy, upstream): not-affected 2, released 2, DNE 1, pending 1.
OpenStack Compute (Nova) before 2013.1.3 and Havana before havana-2 does not properly enforce the os-flavor-access:is_public property, which allows remote authenticated users to obtain sensitive information (flavor properties), boot arbitrary flavors, and possibly have other unspecified impacts by guessing the flavor id.
