Resúmen: SELinux is preventing /home/Guma/Matlab/iso/update/bin/glnx86/xsetup from making the program stack executable. Descripción Detallada: The xsetup 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 xsetup 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 xsetup to run correctly, you can change the context of the executable to execmem_exec_t. "chcon -t execmem_exec_t '/home/Guma/Matlab/iso/update/bin/glnx86/xsetup'" You must also change the default file context files on the system in order to preserve them even on a full relabel.
