You can look at policy generated by audit2allow -M to see this. Most of the problems you are talking about are from libraries requesting more privs then they require execmod. You can change the file context on those files to tell selinux to allow the access. chcon -t textrel_shlib_t LIBRARY http://people.redhat.com/drepper/selinux-mem.html Explains the risks of the exec* accesses. Any time you see this, it should be reported as a problem with SELinux policy but also reported back to the package maintainer, as they might have a problem with their library.
