Description of problem:
Just launch Cossacks 3 game from steam library
SELinux is preventing cossacks from using the 'execheap' accesses on a process.

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

If you do not think cossacks 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.
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.

setsebool -P selinuxuser_execheap 1

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

If you believe that cossacks 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.
allow this access for now by executing:
# ausearch -c 'cossacks' --raw | audit2allow -M my-cossacks
# semodule -X 300 -i my-cossacks.pp
