+They offer an rss feed to get the index of advisories. Each alert has different headings depending on the type, but there are some common ones:
+Summary heading has a table in it which seems to have info about the vuln. that table has these three headings: 'vulnerability_type, remotely_exploitable, impact'
+Mitigation heading as well seems to be common across alerts/advisories.
