3. Description:
The policycoreutils packages contain the core policy utilities required to
manage a SELinux environment.
Security Fix(es):

vulnerable to a TIOCSTI ioctl attack. A specially crafted program executed
via the sandbox command could use this flaw to execute arbitrary commands
in the context of the parent shell, escaping the sandbox. (CVE-2016-7545)
4. Solution:
