Summary:

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

Detailed Description:

The epiphany 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 epiphany 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 epiphany to continue, you must turn on the allow_execheap boolean.
Note: This boolean will affect all applications on the system.

The following command will allow this access:

setsebool -P allow_execheap=1
