Security update for glibc

Open Source Vulnerabilities SUSE-SU-2016:0471-1

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
