Ubuntu 11.10 / 12.04 LTS : nova vulnerability (USN-1438-1)

Low Nessus Plugin ID 58986


The remote Ubuntu host is missing a security-related patch.


Dan Prince discovered that Nova did not enforce quotas for security groups and rules added to security groups. An authenticated user could exploit this to cause a denial of service.

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.


Update the affected python-nova package.
