Subject: [Announce] GnuPG 2.2.17 released to mitigate attacks on keyservers
Message-ID: <87ftnfi6hd.fsf@wheatstone.g10code.de>
Hello!
We are pleased to announce the availability of a new GnuPG release:
version 2.2.17. This is maintenance release to mitigate the effects of
the denial-of-service attacks on the keyserver network. See below for a
list changes.
About GnuPG
===========
The GNU Privacy Guard (GnuPG, GPG) is a complete and free implementation
of the OpenPGP and S/MIME standards.
GnuPG allows to encrypt and sign data and communication, features a
versatile key management system as well as access modules for public key
directories. GnuPG itself is a command line tool with features for easy
integration with other applications. The separate library GPGME provides
a uniform API to use the GnuPG engine by software written in common
programming languages. A wealth of frontend applications and libraries
making use of GnuPG are available. As an universal crypto engine GnuPG
provides support for S/MIME and Secure Shell in addition to OpenPGP.
GnuPG is Free Software (meaning that it respects your freedom). It can
be freely used, modified and distributed under the terms of the GNU
General Public License.
Noteworthy changes in version 2.2.17
====================================
* gpg: Ignore all key-signatures received from keyservers. This
change is required to mitigate a DoS due to keys flooded with
faked key-signatures. The old behaviour can be achieved by adding
keyserver-options no-self-sigs-only,no-import-clean
to your gpg.conf. [#4607]
* gpg: If an imported keyblocks is too large to be stored in the
keybox (pubring.kbx) do not error out but fallback to an import
using the options "self-sigs-only,import-clean". [#4591]
* gpg: New command --locate-external-key which can be used to
refresh keys from the Web Key Directory or via other methods
configured with --auto-key-locate.
* gpg: New import option "self-sigs-only".
* gpg: In --auto-key-retrieve prefer WKD over keyservers. [#4595]
* dirmngr: Support the "openpgpkey" subdomain feature from
draft-koch-openpgp-webkey-service-07. [#4590].
* dirmngr: Add an exception for the "openpgpkey" subdomain to the
CSRF protection. [#4603]
* dirmngr: Fix endless loop due to http errors 503 and 504. [#4600]
* dirmngr: Fix TLS bug during redirection of HKP requests. [#4566]
* gpgconf: Fix a race condition when killing components. [#4577]
Release-info: https://dev.gnupg.org/T4606
Getting the Software
====================
Please follow the instructions found at or
read on:
GnuPG 2.2.17 may be downloaded from one of the GnuPG mirror sites or
direct from its primary FTP server. The list of mirrors can be found at
. Note that GnuPG is not
available at ftp.gnu.org.
The GnuPG source code compressed using BZIP2 and its OpenPGP signature
are available here:
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-2.2.17.tar.bz2 (6560k)
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-2.2.17.tar.bz2.sig
An installer for Windows without any graphical frontend except for a
very minimal Pinentry tool is available here:
https://gnupg.org/ftp/gcrypt/binary/gnupg-w32-2.2.17_20190709.exe (4185k)
https://gnupg.org/ftp/gcrypt/binary/gnupg-w32-2.2.17_20190709.exe.sig
The source used to build the Windows installer can be found in the same
directory with a ".tar.xz" suffix.
A new version of Gpg4win incluing this version of GnuPG will be released
in a few days.
Checking the Integrity
======================
In order to check that the version of GnuPG which you are going to
install is an original and unmodified one, you can do it in one of
the following ways:
* If you already have a version of GnuPG installed, you can simply
verify the supplied signature. For example to verify the signature
of the file gnupg-2.2.17.tar.bz2 you would use this command:
gpg --verify gnupg-2.2.17.tar.bz2.sig gnupg-2.2.17.tar.bz2
This checks whether the signature file matches the source file.
You should see a message indicating that the signature is good and
made by one or more of the release signing keys. Make sure that
this is a valid key, either by matching the shown fingerprint
against a trustworthy list of valid release signing keys or by
checking that the key has been signed by trustworthy other keys.
See the end of this mail for information on the signing keys.
* If you are not able to use an existing version of GnuPG, you have
to verify the SHA-1 checksum. On Unix systems the command to do
this is either "sha1sum" or "shasum". Assuming you downloaded the
file gnupg-2.2.17.tar.bz2, you run the command like this:
sha1sum gnupg-2.2.17.tar.bz2
and check that the output matches the next line:
12c1cee8871c03f0315fc8f27876364b75c95b12 gnupg-2.2.17.tar.bz2
533deef5939fcd6506be650731dea4a9d18f9df8 gnupg-w32-2.2.17_20190709.tar.xz
82abfbc79d1a99b27f25ba92fe878cad07a31532 gnupg-w32-2.2.17_20190709.exe
Internationalization
====================
This version of GnuPG has support for 26 languages with Chinese
(traditional and simplified), Czech, French, German, Japanese,
Norwegian, Polish, Russian, and Ukrainian being almost completely
translated.
Documentation and Support
=========================
If you used GnuPG in the past you should read the description of
changes and new features at doc/whats-new-in-2.1.txt or online at
https://gnupg.org/faq/whats-new-in-2.1.html
The file gnupg.info has the complete reference manual of the system.
Separate man pages are included as well but they miss some of the
details available only in thee manual. The manual is also available
online at
https://gnupg.org/documentation/manuals/gnupg/
or can be downloaded as PDF at
https://gnupg.org/documentation/manuals/gnupg.pdf .
You may also want to search the GnuPG mailing list archives or ask on
the gnupg-users mailing list for advise on how to solve problems. Most
of the new features are around for several years and thus enough public
experience is available. https://wiki.gnupg.org has user contributed
information around GnuPG and relate software.
In case of build problems specific to this release please first check
https://dev.gnupg.org/T4509 for updated information.
Please consult the archive of the gnupg-users mailing list before
reporting a bug: .

Release-info: https://dev.gnupg.org/T4683
Download
========
Source code is hosted at the GnuPG FTP server and its mirrors as listed
at . On the primary server
the source tarball and its digital signature are:
https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.8.5.tar.bz2
https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.8.5.tar.bz2.sig
or gzip compressed:
https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.8.5.tar.gz
https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.8.5.tar.gz.sig
In order to check that the version of Libgcrypt you downloaded is an
original and unmodified file please follow the instructions found at
. In short, you may
use one of the following methods:
- Check the supplied OpenPGP signature. For example to check the
signature of the file libgcrypt-1.8.5.tar.bz2 you would use this
command:
gpg --verify libgcrypt-1.8.5.tar.bz2.sig libgcrypt-1.8.5.tar.bz2
This checks whether the signature file matches the source file.
You should see a message indicating that the signature is good and
made by one or more of the release signing keys. Make sure that
this is a valid key, either by matching the shown fingerprint
against a trustworthy list of valid release signing keys or by
checking that the key has been signed by trustworthy other keys.
See the end of this mail for information on the signing keys.
- If you are not able to use an existing version of GnuPG, you have
to verify the SHA-1 checksum. On Unix systems the command to do
this is either "sha1sum" or "shasum". Assuming you downloaded the
file libgcrypt-1.8.5.tar.bz2, you run the command like this:
sha1sum libgcrypt-1.8.5.tar.bz2
and check that the output matches the first line from the
this list:
2d8781e92f88706707a1e76fb628b499ad538a30 libgcrypt-1.8.5.tar.bz2
c4852a14b57744b2d0e97d9e8e3e60c95ef7e6bb libgcrypt-1.8.5.tar.gz
You should also verify that the checksums above are authentic by
matching them with copies of this announcement. Those copies can be
found at other mailing lists, web sites, and search engines.

Hi,
The GnuPG Project is pleased to announce the availability of Scute
1.6.0.
Scute is a PKCS#11 module built around the GnuPG Agent and the GnuPG
Smart Card Daemon. It allows you to use an OpenPGP or a PIV smart card
for TLS client authentication and S/MIME mail and document signing.
Noteworthy changes in version 1.6.0 (2019-09-10)
===================================
* PIV cards are now supported in addition to OpenPGP cards.
* Key selection is delegated to GpgSM, resulting in faster operations.
* The license has been changed to the GNU Lesser General Public License,
