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

Ubuntu 6.06 LTS:
  quagga                          0.99.2-1ubuntu3.3

Ubuntu 6.10:
  quagga                          0.99.4-4ubuntu1.2

Ubuntu 7.04:
  quagga                          0.99.6-2ubuntu3.2

It was discovered that Quagga did not correctly verify OPEN messages or
COMMUNITY attributes sent from configured peers. Malicious authenticated
remote peers could send a specially crafted message which would cause
bgpd to abort, leading to a denial of service.
