CVE-2016-3706

Published: 10 June 2016

Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in the GNU C Library (aka glibc or libc6) allows remote attackers to cause a denial of service (crash) via vectors involving hostent conversion. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-4458.

From the Ubuntu Security Team

Michael Petlan discovered an unbounded stack allocation in the getaddrinfo() function of the GNU C Library. An attacker could use this to cause a denial of service.
