CVE-2016-1245

moderate-risk
Published 2017-02-22

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.

Do I need to act?
