Description Mikhail 2014-03-27 16:39:38 UTC
Description of problem:
SELinux is preventing /opt/google/chrome/nacl_helper from 'execute' accesses on the file .

*****  Plugin chrome (98.5 confidence) suggests   ****************************

If you want to use the plugin package
Then you must turn off SELinux controls on the Chrome plugins.
Do
# setsebool -P unconfined_chrome_sandbox_transition 0

*****  Plugin catchall (2.46 confidence) suggests   **************************

If you believe that nacl_helper should be allowed execute access on the  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 nacl_helper /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
