It is already disabled. I've found a new thread on RedHat's site that indeed the new patch breaks various type of process creation syscalls (like exec, system(), etc.). I tried raising the stack size as they suggest, but it does not help.

Hello,

  Due to the recent security issues I did an update to my centos  7.3 system which runs Freeswitch 1.6.17/18 (two systems); The main packages updated were the kernel and Libc. Since then, os.execute stopped working inside lua called scripts (luarun api); they fail with error 32512 which means that the command is not available. However, before the upgrade it worked, and so works the command itself when I run it from bash.

Any idea? Some permissions has been changed at the security update?

          Thanks, __Yehavi:
