From ${URL} : A stack (frame) overflow flaw, leading to denial of service (application crash), was found in the way getaddrinfo() routine (returning a list of address structures for particular request) of glibc, the collection of GNU libc libraries, processed certain requests. If an application linked against glibc accepted untrusted getaddrinfo() input remotely, a remote attacker could issue a specially-crafted request, which once processed would lead to that application crash.

CVE-2013-1914 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-1914): Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in GNU C Library (aka glibc or libc6) 2.17 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 domain conversion results.
Fix is in 2.18: http://sourceware.org/git/?p=glibc.git;a=blob_plain;f=NEWS;hb=HEAD
no plans to backport to glibc-2.17 or older
Maintainer(s), please drop the vulnerable version(s). Added to an existing GLSA Request.
