Summary:

SELinux is preventing /usr/local/nctuns/bin/nctunsse from loading
/usr/local/nctuns/lib/libawp.so which requires text relocation.

Detailed Description:

The nctunsse application attempted to load /usr/local/nctuns/lib/libawp.so which
requires text relocation. This is a potential security problem. Most libraries
do not need this permission. Libraries 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. You can configure SELinux temporarily to allow
/usr/local/nctuns/lib/libawp.so to use relocation as a workaround, until the
library is fixed. Please file a bug report.

Allowing Access:

If you trust /usr/local/nctuns/lib/libawp.so to run correctly, you can change
the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/usr/local/nctuns/lib/libawp.so'" You must also change the default file context
files on the system in order to preserve them even on a full relabel. "semanage
fcontext -a -t textrel_shlib_t '/usr/local/nctuns/lib/libawp.so'"

Fix Command:

chcon -t textrel_shlib_t '/usr/local/nctuns/lib/libawp.so'
