With the maturity of sensing, computing, and communication technologies, the Internet of Things (IoT) will be more and more widely used in various industries. Gartner, a market research agency, predicts that endpoints of the IoT will grow at a 33% CAGR from 2015 through 2020, reaching an installed base of 20.4 billion units, with almost two-thirds of them consumer applications. Spending on networked consumer and business endpoints will displace non-networked, growing at a 20% CAGR to $2.9 trillion.
OpenSSH contains a memory exhaustion issue during key exchange. An unauthenticated client can increase the memory allocated to each connection on the server to 384 MB, by repeating the KEXINIT process. An attacker can exploit this vulnerability by initiating multiple connections, to exhaust memory resources of the server and therefore lead to a denial of service.
