Updated glibc packages fix security vulnerabilities:
It was found that glob implementation in glibc does not correctly handle overlong names in struct dirent buffers when GLOB_ALTDIRFUNC is used, causing large stack-based buffer overflow with controlled length and content (CVE-2016-1234).
A stack overflow vulnerability (unbounded allocation) in _nss_dns_getnetbyname_r function was found (CVE-2016-3075).
stack (frame) overflow in getaddrinfo() when called with AF_INET, AF_INET6 (incomplete fix for CVE-2013-4458) (CVE-2016-3706).
