CVE-2017-16227 Open this link in a new tabHow to fix?
Upgrade Debian:9 quagga to version 1.1.1-3+deb9u1 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 aspath_put function in bgpd/bgp_aspath.c in Quagga before 1.2.2 allows remote attackers to cause a denial of service (session drop) via BGP UPDATE messages, because AS_PATH size calculation for long paths counts certain bytes twice and consequently constructs an invalid message.
