CVE-2017-16227 (opens in a new tab)How to fix?
There is no fixed version for Centos:6 quagga-devel.
NVD Description
Note: Versions mentioned in the description apply only to the upstream quagga-devel package and not the quagga-devel package as distributed by Centos.
See How to fix? for Centos:6 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.
