I think that machine is supported by the hplip project's hpaio backend? I notice that the fedora changelog for that package says:
* Wed Sep 18 2013 Tim Waugh <twaugh at redhat.com> - 3.13.9-2 - Applied patch to avoid unix-process authorization subject when using polkit as it is racy (bug #1009541, CVE-2013-4325). So I wonder if the bug is in hpaio? allan On Sun, Dec 8, 2013 at 8:09 AM, Carlos Jacobo Puga Medina <cjpugmed at gmail.com> wrote: > Hello everyone, > > I have one question regarding sane-"backendname" user permissions.
