This is fixed upstream in the 1.x branch: http://git.fedorahosted.org/cgit/tuned.git/patch/?id=c89ad2149ce0425ff790e9c44f5b682e1eee4edc This does not affect 2.2.x, so Fedora 18 is not affected by this issue, however it does affect Fedora 17 (tuned/utils/daemon.py: _daemonize_fork()). Created tuned tracking bugs for this issue Affects: fedora-17 [bug 918233] Acknowledgements: Red Hat would like to thank Finke Lamein for reporting this issue.

It's affected, but the code is different. (In reply to comment #7) > Do we need another CVE? Fedora 17 is affected by security bug 845336. That should have had its own CVE to begin with. I'll sort this out later today and get one assigned.

I still haven't got it, please see the analysis in bug 918233 comment 6. |
Finke Lamein reported that tuned's ktune service, which calls pmqos-static.py when the latency-performance profile is selected, would create its PID file with insecure permissions (0666). A local user could use this flaw to kill arbitrary running processes when the ktune service is stopped. NOTE: the latency-performance profile is not a default, and requires root privileges to enable ("tuned-adm profile latency-performance"). As well, ktune is not enabled by default.
