A security vulnerability in the TCP implementation of Solaris 8, 9 and 10 may allow a remote unprivileged user to cause a Solaris system which is undergoing a "TCP SYN" flood condition to be slow to accept new network connections.�� Such network connections may time out without establishing a connection.�� This would lead to a Denial of Service (DoS) to the network services provided by that system. In addition, a uniprocessor system may also experience overall slowdown due to high CPU usage, resulting in a Denial of Service to the system as a whole.
