3. Description:
The policycoreutils packages contain the core policy utilities required to manage a SELinux environment.
Security Fix(es):
* It was found that the sandbox tool provided in policycoreutils was 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)
