I've just updated the version of OpenSSH to 3.7.1p2-1.

This is again an official new release, this time mostly a bugfix
and security related release.  Since the latest Cygwin specific changes
are now in the official repository, this Cygwin version is from the
vanilla sources again.

Official Release Message:
Portable OpenSSH 3.7.1p2  has just been released. It will be available
from the mirrors listed at http://www.openssh.com/portable.html shortly.

Please note that this is a release to address issues in the portable
version only. The items mentioned below do not affect the OpenBSD

OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0
implementation and includes sftp client and server support.

We would like to thank the OpenSSH community for their continued
support to the project, especially those who contributed source and
bought T-shirts or posters.

We have a new design of T-shirt available, more info on

Security Changes:

  Portable OpenSSH version 3.7p1 and 3.7.1p1 contain multiple
  vulnerabilities in the new PAM authentication code. At least one of 
  these bugs is remotely exploitable (under a non-standard
  configuration, with privsep disabled).

  OpenSSH 3.7.1p2 fixes these bugs. Please note that these bugs do not
  exist in OpenBSD's releases of OpenSSH.

Changes since OpenSSH 3.7.1p1:

* This release disables PAM by default. To enable it, set "UsePAM yes" in
  sshd_config. Due to complexity, inconsistencies in the specification and
  differences between vendors' PAM implementations we recommend that PAM
  be left disabled in sshd_config unless there is a need for its use.
  Sites using only public key or simple password authentication usually
  have little need to enable PAM support.

* This release now requires zlib 1.1.4 to build correctly. Previous
  versions have security problems.

* Fix compilation for versions of OpenSSL before 0.9.6. Some cipher modes
  are not supported for older OpenSSL versions.

* Fix compilation problems on systems with a missing or lacking inet_ntoa()

* Workaround problems related to unimplemented or broken setresuid/setreuid
  functions on several platforms.

* Fix compilation on older OpenBSD systems.

* Fix handling of password-less authentication (PermitEmptyPasswords=yes)
  that has not worked since the 3.7p1 release.
