CVE-2016-3706 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 5.81% chance of exploitation in the next 30 days.
