==========================================================
A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 8.04 LTS
Ubuntu 8.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  quagga                          0.99.2-1ubuntu3.6

Ubuntu 8.04 LTS:
  quagga                          0.99.9-2ubuntu1.3

Ubuntu 8.10:
  quagga                          0.99.9-6ubuntu0.2

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

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.

Original advisory details:

 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.
