Default Realplayer problem

Hi


Summary:

SELinux is preventing the plugin-config (nsplugin_config_t) from executing
/opt/real/RealPlayer/mozilla/nphelix.so.

Detailed Description:

SELinux has denied the plugin-config from executing
/opt/real/RealPlayer/mozilla/nphelix.so. If plugin-config is supposed to
be able

to execute /opt/real/RealPlayer/mozilla/nphelix.so, this could be a labeling
problem. Most confined domains are allowed to execute files labeled
bin_t. So
you could change the labeling on this file to bin_t and retry the
application.

If this plugin-config is not supposed to execute
/opt/real/RealPlayer/mozilla/nphelix.so, this could signal a intrusion
attempt.


Allowing Access:

If you want to allow plugin-config to execute
/opt/real/RealPlayer/mozilla/nphelix.so: chcon -t bin_t
'/opt/real/RealPlayer/mozilla/nphelix.so' If this fix works, please
update the
file context on disk, with the following command: semanage fcontext -a
-t bin_t
'/opt/real/RealPlayer/mozilla/nphelix.so' Please specify the full path
to the

executable, Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this
selinux-policy

to make sure this becomes the default labeling.
