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)

 

4. Solution:
