Bug 702942

SELinux is preventing /usr/bin/Xorg (deleted) from using the 'execmem' accesses on a process.

*****  Plugin catchall_boolean (32.5 confidence) suggests  *******************

If you want to allows XServer to execute writable memory
Then you must tell SELinux about this by enabling the 'allow_xserver_execmem' boolean.
Do
setsebool -P allow_xserver_execmem 1

*****  Plugin catchall_boolean (32.5 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_boolean (32.5 confidence) suggests  *******************

If you want to allow unconfined executables to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla
Then you must tell SELinux about this by enabling the 'allow_execmem' boolean.
Do
setsebool -P allow_execmem 1

*****  Plugin catchall (4.5 confidence) suggests  ****************************

If you believe that Xorg (deleted) should be allowed execmem access on processes labeled xserver_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 X /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
