The Ubuntu security notices web page has an option to show only notices for a single release. Is there a way to get notices for a single release as a feed, without setting it up myself? That is, is there an official feed containing all and only Ubuntu 12.04 (for example) security notices?
The end goal is a tool which warns when any of a set of packages (not necessarily the ones installed on a system) for a single Ubuntu release are affected by a security notice.
