:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that gnome-shell should be allowed execute access on the vlc file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep gnome-shell /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Daniel Walsh 2011-10-13 17:34:34 UTC
Any idea why gdm gnome shell would try to execute /usr/bin/vlc?

Comment 2 Rob 2011-10-13 20:34:57 UTC
Nope this was in a middle of an update using yumex, vlc was not active nor being updated. 

Though i have just noticed in the report its happened more than i thought, i thought only once, but i haven't used vlc at all since it first started. Only installed yesterday so just been installing stuff and playing around with f16

Comment 3 Miroslav Grepl 2011-10-14 11:58:43 UTC
Dan, this does access check

syscall=access


and looks this is an issue with yumex during an update.

Comment 4 Daniel Walsh 2011-10-14 13:28:00 UTC
Yes I just checked in a dontaudit access_check for this.
