Details with npviewer.bin
##################################################################################
SELinux is preventing /usr/lib64/nspluginwrapper/npviewer.bin from execute access on the file /usr/lib64/mozilla/plugins/libflashplayer.so.
***** Plugin restorecon (99.5 confidence) suggests *************************
If you want to fix the label.
/usr/lib64/mozilla/plugins/libflashplayer.so default label should be lib_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /usr/lib64/mozilla/plugins/libflashplayer.so
***** Plugin catchall (1.49 confidence) suggests ***************************
If you believe that npviewer.bin should be allowed execute access on the libflashplayer.so 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 npviewer.bin /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
