11 October 2012

Quagga could be made to crash if it received specially crafted network traffic.

It was discovered that Quagga incorrectly handled certain malformed
messages. A remote attacker could use this flaw to cause Quagga to crash,
resulting in a denial of service.

Update instructions

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

Ubuntu 12.04

After a standard system update you need to restart Quagga to make all the
necessary changes.
