High impact if exploited, but EPSS currently rates exploitation as unlikely (3.66%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
It was discovered that the zebra daemon in Quagga before 1.0.20161017 suffered from a stack-based buffer overflow when processing IPv6 Neighbor Discovery messages. The root cause was relying on BUFSIZ to be compatible with a message size; however, BUFSIZ is system-dependent.
