The UK's National Infrastructure Security Co-ordination Centre has advised users to update their internet communications infrastructure to plug a denial-of-service vulnerability in major suppliers' equipment.

Cisco, Juniper Networks and IBM have already admitted to the problem and have issued patches to prevent the threat, which can lead to organisations' networks crashing from a remote denial of service attack.

The threat involves network routers failing to handle internet traffic supported by the internet control message protocol and the transmission connection protocol.

Hackers could use the protocols to launch a remote attack and crash corporate networks, said the NISCC.
