Bug 668281

SOMETIMES SAME ALERT IS INVOKED WHEN STARTING PIDGIN TOO.
---------------------------------------------------------
SELinux is preventing /usr/bin/nautilus from using the execstack access on a process.

*****  Plugin allow_execstack (53.1 confidence) suggests  ********************

If you do not think /usr/bin/nautilus should need to map stack memory that is both writable and executable.
Then you need to report a bug. This is a potentially dangerous access.
Do
contact your security administrator and report this issue.

*****  Plugin catchall_boolean (42.6 confidence) suggests  *******************

If you want to allow unconfined executables to make their stack executable.  This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla
Then you must tell SELinux about this by enabling the 'allow_execstack' boolean.
Do
setsebool -P allow_execstack 1

*****  Plugin catchall (5.76 confidence) suggests  ***************************

If you believe that nautilus should be allowed execstack access on processes labeled unconfined_t 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 /usr/bin/nautilus /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
