Updated: unzip-5.50-2


The 'unzip' package has been updated to version 5.50-1.  UnZip
is an open-source, command-line alternative to other zip-format
archives such as WinZip, etc.  unzip-5.50 is the latest release
from Info-Zip, http://www.info-zip.org/pub/infozip/UnZip.html.

CHANGES from 5.50-1

o Add fix for an obscure directory traversal bug
  (thanks to David F.)
o See other NOTES below.

--Chuck Wilson

INSTALLATION:

To update your installation, click on the "Install Cygwin now" link
on the http://cygwin.com/ web page.  This downloads setup.exe to your
system.  Then, run setup and update the unzip package.

Note that we have recently stopped 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.

In the UK,
http://programming.ccp14.ac.uk/ftp-mirror/programming/cygwin/pub/cygwin/
is usually up-to-date within 48 hours.

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.

If you have questions or comments, please send them to the Cygwin
mailing list at: cygwin at cygwin dot com .  I would appreciate if you would
use this mailing list rather than emailing me directly.  This includes
ideas and comments about the setup utility or Cygwin in general.

If you want to make a point or ask a question, the Cygwin mailing list
is the appropriate place.

NOTES:

o This package WAS built with decryption support -- although the
corresponding zip package does NOT include ENcryption support. The
unzip-5.50 code base contains decryption support by default, without
using the zcrypt29.zip package at http://www.info-zip.org/pub/infozip/.

Blame US cryptography export law; at present, the export of decryption
binaries and source code is allowed, while exporting encryption source
code still requires explicit notification of the US govt. Further, exporting compiled binaries of open-source code requires a formal technical review from the US Bureau of Export Administration. See:
http://www.cdt.org/crypto/admin/
http://www.cdt.org/crypto/admin/000114qanda.shtml
http://www.columbia.edu/~ariel/jlewis-answers.html


o this build is -mno-win32 clean; that is, it builds from source
identically, regardless of whether gcc sets the _WIN32 or WINNT
defines.
