Two new versions of socat are available in the Cygwin distribution: - current
  2.0.0b5-1 - test

These are new upstream releases, that address a security vulnerability in
previous versions.  You can read the upstream changelog at
http://www.dest-unreach.org/socat/doc/CHANGES.  Because this is a security
update, previous versions of socat have been removed from the Cygwin archive.

socat is a relay for bidirectional data transfer between two independent data
channels. Each of these data channels may be a file, pipe, device (serial line
etc. or a pseudo terminal), a socket (UNIX, IP4, IP6 - raw, UDP, TCP), an SSL
socket, proxy CONNECT connection, a file descriptor (stdin etc.), the GNU line
editor (readline), a program, or a combination of two of these. These modes
include generation of 'listening' sockets, named pipes, and pseudo terminals.
socat can be used, e.g., as TCP port forwarder (one-shot or daemon), as an
external socksifier, for attacking weak firewalls, as a shell interface to UNIX
sockets, IP6 relay, for redirecting TCP oriented programs to a serial line, to
logically connect serial lines on different computers, or to establish a
relatively secure environment (su and chroot) for running client or server shell
scripts with network connections.
