Summary: SELinux is preventing /usr/bin/gs "execstack" access. Detailed Description: SELinux denied access requested by gs. It is not expected that this access is required by gs and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug report.

This looks like you might have some bad libraries on your system. Cups and gs should not need execstack. Do you have some closed source drivers or shared libraries installed? nvidia drivers? rpmfusion codecs? These are built incorrectly and require a dangerous priv execstack. This link http://people.redhat.com/~drepper/selinux-mem.html explains the access. You can use the command execstack -q to try to find the libraries with the execstack flag on, I use a command like find /usr/lib64 -name \*.so\* -exec execstack -q {} \; -print | grep ^X Then try to turn off the flag of any libraries that require execstack execstack -c And see if the apps work.
