Description of problem:
SELinux is preventing maxima from changing the access protection of memory on the heap.

Version-Release number of selected component (if applicable):
maxima-5.17.1-7.fc11.i586
maxima-gui-5.17.1-7.fc11.i586
maxima-runtime-gcl-5.17.1-7.fc11.i586


How reproducible:
Every time wxMaxima is started.

Steps to Reproduce:
1. launch Application->Programming->wxMaxima
2.
3.
  
Actual results:
Appliation does start and appears to be operational.
SELinux troubleshooter icon appears in desktop bar.

Expected results:
Application should work within SELinux not violate it.

Summary:

SELinux is preventing maxima from changing the access protection of memory on
the heap.

Detailed Description:

The maxima application attempted to change the access protection of memory on
the heap (e.g., allocated using malloc). This is a potential security problem.
Applications should not be doing this. Applications are sometimes coded
incorrectly and request this permission. The SELinux Memory Protection Tests
(http://people.redhat.com/drepper/selinux-mem.html) web page explains how to
remove this requirement. If maxima does not work and you need it to work, you
can configure SELinux temporarily to allow this access until the application is
fixed. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

Allowing Access:

If you want maxima to continue, you must turn on the allow_execheap boolean.
Note: This boolean will affect all applications on the system.

Fix Command:

setsebool -P allow_execheap=1
