Upgrade Debian:9 quagga to version 0.96.4x-4 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream quagga package and not the quagga package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
The vty layer in Quagga before 0.96.4, and Zebra 0.93b and earlier, does not verify that sub-negotiation is taking place when processing the SE marker, which allows remote attackers to cause a denial of service (crash) via a malformed telnet command to the telnet CLI port, which may trigger a null dereference.
