CVE-2016-3706
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.93%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
