PuTTY 0.67 is released

[Simon Tatham]

PuTTY version 0.67 is released
------------------------------

All the pre-built binaries, and the source code, are now available
from the PuTTY website at

    http://www.chiark.greenend.org.uk/~sgtatham/putty/

This is a SECURITY UPDATE. We recommend that everybody upgrade, as
soon as possible.

This release fixes a security hole in PSCP, in the old-style SCP
protocol. A server sending a malformed header before the contents of
the file could overrun a buffer exploitably in PSCP. [CVE-2016-2563]

In addition to fixing that vulnerability, this release has other
security-related updates:

 - Windows PuTTY now sets its process ACL more restrictively, in an
   attempt to defend against malicious other processes reading
   sensitive data out of its memory.

 - We have started using Authenticode to sign our Windows executables
   and installer. They should show a verified publisher name of 'Simon
   Tatham'.

 - Assorted other fixes for crash-type bugs (but none known to be
   exploitable).

Enjoy using PuTTY!

Cheers,
Simon
