Updated: socat 1.7.2.4-1, 2.0.0-b7-1

[Andrew Schulman <schulman.andrew@epa.gov>]

Two new versions of socat are available in the Cygwin distribution:

  1.7.2.4-1  - current
  2.0.0-b7-1 - test

These are new upstream releases, that address a security vulnerability
(possible buffer overflow) in previous versions.

Security advisory: 
  http://www.dest-unreach.org/socat/contrib/socat-secadv5.txt
Upstream changelog:
  http://www.dest-unreach.org/socat/doc/CHANGES.  

These versions also add IPv6 support (TCP6, TCP6-LISTEN, UDP6,
UDP6-DATAGRAM, ...) for the first time in Cygwin.  This feature hasn't
been tested much yet, so please test and report any findings (good or
bad) here.

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.
