Ubuntu 11.10 / 12.04 LTS : nova regression (USN-1466-2)

high Nessus Plugin ID 59471

Language:

Synopsis

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

Description

USN 1466-1 fixed a vulnerability in Nova. The upstream patch introduced a regression when a security group granted full access and therefore the network protocol was left unset, causing an error in processing. This update fixes the issue.

We apologize for the inconvenience.

It 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.

Solution

Update the affected python-nova package.
