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)
