Bug 562201

Summary:

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

Detailed Description:

The swriter.bin 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 swriter.bin 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 swriter.bin 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
