## Description

Stack-based buffer overflow in the getaddrinfo function in
sysdeps/posix/getaddrinfo.c in GNU C Library (aka glibc or libc6) 2.18 and
earlier allows remote attackers to cause a denial of service (crash) via a
(1) hostname or (2) IP address that triggers a large number of AF\_INET6
address results. NOTE: this vulnerability exists because of an incomplete
fix for CVE-2013-1914.
