DESCRIPTION:
A vulnerability has been reported in Sun Solaris, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error within the TCP
implementation and can be exploited to e.g. cause network connections
to time out or to cause certain systems to consume large amounts of
CPU resources via a TCP SYN flood.

Successful exploitation requires that the ndd(1M) tunable
"tcp_conn_req_max_q0" is set to a value higher than the default value
of 1024.

The vulnerability is reported in Solaris 8, 9, and 10 for both the
SPARC and x86 platforms.
