Fix(es): * An arbitrary command injection flaw was found in the way bash
processed the hostname value. A malicious DHCP server could use this flaw to
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)
