Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
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
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.
