I'm afraid there is no shortcut to going through the list. 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.
