XSA-19 and earlier where older than that, so are not applicable. XSA-20 and newer all specifically refer to xen-4.2-testing and whether it is vulnerable or not. Although now I note that you might have transposed 4.1.2. So the 4.1 release notes puts 4.1.2 on 21 Oct 2011. However, I would highly recomend moving forwards to 4.1.4 or even newer. 4.1.x is in maintenance now and is only receiving bugfixes, but being OS software, there is still a steady stream of bugfixes being backported. ~Andrew

The source repositories would give you the exact order. If you want to start from a clean slate, 4.1.5 and 4.2.2 look like they will come out soon, so you would just need to watch for new security updates after that point to keep them secure.

Each entry contains a link to the advisory. The advisory will contain a description of versions which are affected and the appropriate patches. The list also contains links to the patches applied to the affected trees (at least those which were still security supported at the time). As others have also suggested you can prefilter the list based on publication dates vs the release date of the base version of Xen which you are using since a new stable branch will contain a roll up of the relevant previous security updates. But watch out for the fact that the release dates of the advisories are not monotonically increasing, since sometimes a new issue will go public while another is still in embargo. Ian.
