kernel:         3.6.3-1.fc17.i686

description:
:SELinux is preventing wine-preloader from 'mmap_zero' accesses on the memprotect .
:
:*****  Plugin mmap_zero (53.1 confidence) suggests  **************************
:
:If you do not think wine-preloader should need to mmap low memory in the kernel.
:Then you may be under attack by a hacker, this is a very dangerous access.
:Do
:contact your security administrator and report this issue.
:
:*****  Plugin catchall_boolean (42.6 confidence) suggests  *******************
:
:If you want to mmap_low_allowed
:Then you must tell SELinux about this by enabling the 'mmap_low_allowed' boolean.You can read 'unconfined_selinux' man page for more details.
:Do
:setsebool -P mmap_low_allowed 1
:
:*****  Plugin catchall (5.76 confidence) suggests  ***************************
:
:If you believe that wine-preloader should be allowed mmap_zero access on the  memprotect 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 wine-preloader /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
