Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc
functions in the libresolv library in the GNU C Library (aka glibc or
libc6) before 2.23 allow remote attackers to cause a denial of service
(crash) or possibly execute arbitrary code via a crafted DNS response that
triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6
address family, related to performing "dual A/AAAA DNS queries" and the
libnss_dns.so.2 NSS module.
