Description Paulo Sedrez 2011-10-28 20:16:30 UTC
SELinux is preventing /opt/google/chrome/nacl_helper_bootstrap from 'execute_no_trans' accesses on the file /opt/google/chrome/nacl_helper_bootstrap.

*****  Plugin catchall (100. confidence) suggests  ***************************

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