Ubuntu 6.06 LTS / 8.04 LTS / 8.10 : quagga regression (USN-775-2)

Ubuntu Security Notice (C) 2009-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

USN-775-1 fixed vulnerabilities in Quagga. The preventative fixes
introduced in Quagga prior to Ubuntu 9.04 could result in BGP service
failures. This update fixes the problem.

We apologize for the inconvenience.

It was discovered that the BGP service in Quagga did not correctly
handle certain AS paths containing 4-byte ASNs. An authenticated
remote attacker could exploit this flaw to cause bgpd to abort,
leading to a denial of service.

Solution :

Update the affected quagga and / or quagga-doc packages.

Risk factor :

High
