   An update that solves 6 vulnerabilities and has three fixes
   is now available.

Description:


   This update for glibc fixes the following security 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)

   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

   This update was imported from the SUSE:SLE-12-SP1:Update update project.
