Description of problem:


SELinux is preventing wine-preloader from using the execheap access on
a process.

*****  Plugin allow_execheap (53.1 confidence) suggests
********************

If you do not think wine-preloader should need to map heap 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 selinuxuser to execheap
Then you must tell SELinux about this by enabling the
'selinuxuser_execheap' boolean.

Do
setsebool -P selinuxuser_execheap 1

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

If you believe that wine-preloader should be allowed execheap 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:
# ausearch -c 'wine-preloader' --raw | audit2allow -M my-winepreloader
# semodule -X 300 -i my-winepreloader.pp
