It was found that getaddrinfo() did not limit the amount of stack memory used during name resolution. An attacker able to make an application resolve an attacker-controlled hostname or IP address could possibly cause the application to exhaust all stack memory and crash.

Description Vincent Danen 2013-10-22 22:41:17 UTC 
A stack (frame) overflow flaw, which led to a denial of service (application crash), was found in the way glibc's getaddrinfo() function processed certain requests when called with AF_INET6.  A similar flaw to CVE-2013-1914, this affects AF_INET6 rather than AF_UNSPEC.

A proposed patch has been submitted for review [1].  No CVE has been assigned yet.
