Title:	Quagga DoS Vulnerability
Summary:	Quagga is prone to a denial of service vulnerability.
Description:	Summary: Quagga is prone to a denial of service vulnerability. Vulnerability Insight: The aspath_put function in bgpd/bgp_aspath.c in Quagga 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 Software/OS: Quagga prior version 1.2.2. Solution: Update to version 1.2.2 or later. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
