Ubuntu 11.10 / 12.04 LTS : nova vulnerability (USN-1466-1)
Medium Nessus Plugin ID 59399
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt was discovered that, when defining security groups in Nova using the EC2 or OS APIs, specifying the network protocol (e.g. 'TCP') in the incorrect case would cause the security group to not be applied correctly. An attacker could use this to bypass Nova security group restrictions.
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.
SolutionUpdate the affected python-nova package.
