:SELinux is preventing /usr/libexec/totem-plugin-viewer from read, write access on the chr_file card0.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that totem-plugin-viewer should be allowed read write access on the card0 chr_file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep totem-plugin-vi /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Did Firefox work without this access?

Comment 2 Amit Shah 2012-01-05 02:38:46 UTC
(In reply to comment #1)
> Did Firefox work without this access?

Yes, it did.

Comment 3 Daniel Walsh 2012-01-05 15:08:13 UTC
I guess we should dontaudit, since this could allow a confined app to attack other X servers.  (I would figure.)
