A local user could use this flaw to\nbypass intended PolicyKit authorizations and escalate their privileges\n(CVE-2013-4288).\n\nNote: Applications that invoke pkcheck with the --process option need to\nbe modified to use the pid,pid-start-time,uid argument for that option, to\nallow pkcheck to check process authorization correctly.\n\nBecause of the change in the PolicyKit API, the spice-gtk (CVE-2013-4324),\nhplip (CVE-2013-4325), rtkit (CVE-2013-4326), and systemd (CVE-2013-4327)\npackages have been updated to use a different API that is not affected by\nthis PolicyKit vulnerability.  The libvirt package will also be updated\nfor the same reason, but this update will come in a separate advisory.\n","status":"published","published":"2013-10-05T17:53:02Z","modified":"2026-04-16T06:24:12.682952618Z","updated_at":"2026-11-02T15:49:39.121227Z"}]}}
