I've updated the version of OpenSSH in cygwin/latest to 3.0.2p1-2.
This is a security update. Only the Cygwin OpenSSH is concerned.
If you're logging in to a Cygwin sshd with version 2 protocol using an
arbitrary user name which is not in /etc/passwd, the forked sshd which
is handling this connection crashes with a segmentation violation. The
client side encounters an immediate disconnect ("Connection reset by
peer"). This could be used by a malicious remote client to enumerate
the user names on the Cygwin server machine.
The Cygwin specific code implicitly dereferences a pointer to a struct
passwd. This pointer can be NULL if the user isn't found in /etc/passwd.
Update to version 3.0.2p1-2.
To update your installation, click on the "Install Cygwin now" link on
the http://sources.redhat.com/cygwin web page. This downloads setup.exe
to your system. The, run setup and answer all of the questions.
Note that we do not allow downloads from sources.redhat.com (aka
cygwin.com) due to bandwidth limitations. This means that you will need
to find a mirror which has this update.
In the US, ftp://mirrors.rcn.net/mirrors/sources.redhat.com/cygwin/ is a
reliable high bandwidth connection.
usually pretty good.
In the UK,

If one of the above doesn't have the latest version of this package then
you can either wait for the site to be updated or find another mirror.
