CVE-2016-3075
Stack-based buffer overflow in the nss_dns implementation of the getnetbyname function in GNU C Library (aka glibc) before 2.24 allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via a long name.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
