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

Ubuntu Security Notice (C) 2009-2016 Canonical, Inc. / NASL script (C) 2009-2016 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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

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

Risk factor :

High
