Description
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.
Affected configurations
• quagga quagga (<= 1.2.1)
• debian debian linux 8.0
• debian debian linux 9.0
