  - CVE-2015-7547: A stack-based buffer overflow in getaddrinfo allowed
  remote attackers to cause a crash or execute arbitrary code via crafted
  and timed DNS responses (bsc#961721)

  - CVE-2015-8777: Insufficient checking of LD_POINTER_GUARD environment
  variable allowed local attackers to bypass the pointer guarding
  protection of the dynamic loader on set-user-ID and set-group-ID
  programs (bsc#950944)

  - CVE-2015-8776: Out-of-range time values passed to the strftime function
  may cause it to crash, leading to a denial of service, or potentially
  disclosure information (bsc#962736)

  - CVE-2015-8778: Integer overflow in hcreate and hcreate_r could have
  caused an out-of-bound memory access. leading to application crashes or,
  potentially, arbitrary code execution (bsc#962737)

  - CVE-2014-9761: A stack overflow (unbounded alloca) could have caused
  applications which process long strings with the nan function to crash
  or, potentially, execute arbitrary code. (bsc#962738)

  - CVE-2015-8779: A stack overflow (unbounded alloca) in the catopen
  function could have caused applications which pass long strings to the
  catopen function to crash or, potentially execute arbitrary code.
  (bsc#962739)

  The following non-security bugs were fixed:

  - bsc#955647: Resource leak in resolver

  - bsc#956716: Don't do lock elision on an error checking mutex

  - bsc#958315: Reinitialize dl_load_write_lock on fork");
