  in some circumstances prevented IPv6 addresses from resolving. This update
  reverts the change in Ubuntu 12.04 LTS. We apologize for the error. Original
  advisory details: It was discovered that the GNU C Library incorrectly handled
  the strxfrm() function. An attacker could use this issue to cause a denial of
  service or possibly execute arbitrary code. This issue only affected Ubuntu
  12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8982) It was discovered that an
  integer overflow existed in the _IO_wstr_overflow() function of the GNU C
  Library. An attacker could use this to cause a denial of service or possibly
  execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu
  14.04 LTS. (CVE-2015-8983) It was discovered that the fnmatch() function in the
  GNU C Library did not properly handle certain malformed patterns. An attacker
  could use this to cause a denial of service. This issue only affected Ubuntu
  12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8984) Alexander Cherepanov discovered
  a stack-based buffer overflow in the glob implementation of the GNU C Library.
  An attacker could use this to specially craft a directory layout and cause a
  denial of service. (CVE-2016-1234) Michael Petlan discovered an unbounded stack
  allocation in the getaddrinfo() function of the GNU C Library. An attacker could
  use this to cause a denial of service. (CVE-2016-3706) Aldy Hernandez discovered
  an unbounded stack allocation in the sunrpc implementation in the GNU C Library.
  An attacker could use this to cause a denial of service. (CVE-2016-4429) Tim
  Ruehsen discovered that the getaddrinfo() implementation in the GNU C Library
  did not properly track memory allocations. An attacker could use this to cause a
  denial of service. This issue only affected Ubuntu 16.04 LTS. (CVE-2016-5417)
  Andreas Schwab discovered that the GNU C Library on ARM 32-bit platforms did not
  properly set up execution contexts. An attacker could use this to cause a denial
  of service. (CVE-2016-6323)");
