  Fix(es): * An arbitrary command injection flaw was found in the way bash

  execute arbitrary commands on the DHCP client machines running bash under
  specific circumstances. (CVE-2016-0634) * An arbitrary command injection flaw
  was found in the way bash processed the SHELLOPTS and PS4 environment variables.
  A local, authenticated attacker could use this flaw to exploit poorly written
  setuid programs to elevate their privileges under certain circumstances.
  (CVE-2016-7543) * A denial of service flaw was found in the way bash handled
  popd commands. A poorly written shell script could cause bash to crash resulting
  in a local denial of service limited to a specific bash session. (CVE-2016-9401)
