Resúmen:

SELinux is preventing /lib/ld-2.11.so from making the program stack executable.

Descripción Detallada:

The ld-linux.so.2 application attempted to make its stack executable. This is a
potential security problem. This should never ever be necessary. Stack memory is
not executable on most OSes these days and this will not change. Executable
stack memory is one of the biggest security problems. An execstack error might
in fact be most likely raised by malicious code. 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 ld-linux.so.2 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.

Permitiendo Acceso:

Sometimes a library is accidentally marked with the execstack flag, if you find
a library with this flag you can clear it with the execstack -c LIBRARY_PATH.
Then retry your application. If the app continues to not work, you can turn the
flag back on with execstack -s LIBRARY_PATH. Otherwise, if you trust
ld-linux.so.2 to run correctly, you can change the context of the executable to
execmem_exec_t. "chcon -t execmem_exec_t '/lib/ld-2.11.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 execmem_exec_t '/lib/ld-2.11.so'"

Comando para Corregir:

chcon -t execmem_exec_t '/lib/ld-2.11.so'
