The Finnish Computer Emergency Response Team (CERT-FI) has released an alert which lists a number of vendors that have reported vulnerability to a new Denial of Service (DoS) vulnerability.  A DoS attack on the flaw can cause network devices to crash or lockup generating service outages for your network.

The vulnerability was discovered by researchers utilising a testing tool known as Sockstress, but can be replicated by flooding a device with specially crafted data packets (TCP packets in particular).

Below is a list of the affected vendors and links to their alerts:

The vulnerability is quite widespread so it is recommended to apply vendor patches as soon as possible to limit potential risk.
