Selinux alert info:

Summary:

SELinux has prevented wine from performing an unsafe memory operation.

Detailed Description:

SELinux denied an operation requested by wine-preloader, a program used to run
Windows applications under Linux. This program is known to use an unsafe
operation on system memory but so are a number of malware/exploit programs which
masquerade as wine. If you were attempting to run a Windows program your only
choices are to allow this operation and reduce your system security against such
malware or to refrain from running Windows applications under Linux. If you were
not attempting to run a Windows application this indicates you are likely being
attacked by some for of malware or program trying to exploit your system for
nefarious purposes. Please refer to
http://wiki.winehq.org/PreloaderPageZeroProblem Which outlines the other
problems wine encounters due to its unsafe use of memory and solutions to those
problems.

Allowing Access:

If you decide to continue to run the program in question you will need to allow
this operation. This can be done on the command line by executing: # setsebool
-P mmap_low_allowed 1

Fix Command:

/usr/sbin/setsebool -P mmap_low_allowed 1
