ISAKMP Security Advisory: DoS Threat in Major Networking Products

A flaw in a key Internet security protocol used by major networking products could open systems up to denial-of-service (DoS) and other kinds of attacks, experts have warned. Finnish researchers at the University of Oulu announced Monday that they have found a vulnerability in the Internet Security Association and Key Management Protocol, or ISAKMP. The technology is used in IPsec virtual private network and firewall products from a range of networking companies, including giants Cisco and Juniper.

The severity of the problems varies by software vendor, according to an advisory issued jointly by the British National Infrastructure Security Coordination Centre (NISCC) and the Finnish CERT.
