    CVE-2017-16227
    Aliases:
    USN-3471-1

    Summary:

    Details: 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.
