   An update that solves 10 vulnerabilities and has four fixes
   is now available.

Description:

   This update for glibc fixes the following issues:

   - 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)
   - CVE-2013-2207: pt_chown tricked into granting access to another users
     pseudo-terminal (bsc#830257)
   - CVE-2013-4458: Stack (frame) overflow in getaddrinfo() when called with
     AF_INET6 (bsc#847227)
   - CVE-2014-8121: denial of service issue in the NSS backends (bsc#918187)
   - bsc#920338: Read past end of pattern in fnmatch
   - CVE-2015-1781: buffer overflow in nss_dns (bsc#927080)

   The following non-security bugs were fixed:

   - bnc#892065: SIGSEV tst-setlocale3 in glibc-2.11.3-17.68.1
   - bnc#863499: Memory leak in getaddrinfo when many RRs are returned
   - bsc#892065: Avoid unbound alloca in setenv
   - bsc#945779: Properly reread entry after failure in nss_files getent
     function
