security advisory critical Before you close out the week, check what still needs to be patched. . The list is not small. Ubuntu and Red Hat pushed kernel updates. OpenVPN and OpenShift both received security fixes. Several everyday Linux components were patched too, including Vim, nginx, cifs-utils, LibVNCServer, nghttp2, and Perl. That is the kind of week administrators can easily write off as routine. It should not be. These are the updates that keep small openings from turning into real access. Why This Week Looks...
