Description Vincent Danen 2013-03-06 23:32:59 UTC

Aaron Parsons reported [1] that tuned would create its PID file with insecure permissions (0666).  A local user could use this flaw to kill arbitrary running processes when the tuned service is stopped.

This was fixed upstream [2] and was also previously corrected in Red Hat Enterprise Linux 6 via RHBA-2013:0386 [3].

Current Fedora 18 inherited the upstream fix, however Fedora 17 is still affected by this issue.
