From wk на gnupg.org Fri Jun 2 10:31:31 2017 From: wk на gnupg.org (Werner Koch) Date: Fri, 02 Jun 2017 10:31:31 +0200 Subject: [gnupg-ru] [Announce] Libgcrypt 1.7.7 released Message-ID: <87o9u67puk.fsf@wheatstone.g10code.de> Hi! The GnuPG Project is pleased to announce the availability of Libgcrypt version 1.7.7. This is a bug fixing. Libgcrypt is a general purpose library of cryptographic building blocks. It is originally based on code used by GnuPG. It does not provide any implementation of OpenPGP or other protocols. Thorough understanding of applied cryptography is required to use Libgcrypt. Noteworthy changes in version 1.7.7 (2017-06-02) [C21/A1/R7] =================================== * Bug fixes: - Fix possible timing attack on EdDSA session key. - Fix long standing bug in secure memory implementation which could lead to a segv on free. [bug#3027] Download ======== Source code is hosted at the GnuPG FTP server and its mirrors as listed at https://gnupg.org/download/mirrors.html . On the primary server the source tarball and its digital signature are: ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.7.7.tar.bz2 (2794k) ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.7.7.tar.bz2.sig That file is bzip2 compressed. A gzip compressed version is here: ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.7.7.tar.gz (3290k) ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.7.7.tar.gz.sig The same files are also available via HTTP: https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.7.7.tar.bz2 https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.7.7.tar.bz2.sig https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.7.7.tar.gz https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.7.7.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-1.7.7.tar.bz2 you would use this command: gpg --verify libgcrypt-1.7.7.tar.bz2.sig libgcrypt-1.7.7.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-1.7.7.tar.bz2, you run the command like this: sha1sum libgcrypt-1.7.7.tar.bz2 and check that the output matches the first line from the this list: ea4ae1a4dba51f15095319419d7b42a0bf160384 libgcrypt-1.7.7.tar.bz2 fc5b02758dc47fde70a155a05efe9d92a1778f8d libgcrypt-1.7.7.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. Copying ======= Libgcrypt is distributed under the terms of the GNU Lesser General Public License (LGPLv2.1+).

The GnuPG Project today announced the launch of a funding campaign to further support and improve its leading mail and data encryption software, GnuPG. The campaign aims to secure 15000 Euro per month in recurring donations from individual donors to finance the development of their free software. Donations can be made at the newly reworked website: Activists, journalists, lawyers, and many others rely on GnuPG to protect their communication. The software guards emails, files, and programs from government and criminal snooping and spying on Windows, Mac, and Linux. And, more than two-thirds of the servers running the Internet rely on GnuPG to verify the integrity of system updates. Ongoing government spying revelations have shown how little of our information is really safe. GnuPG is one of the few tools that can offer real protection, free of commercial interests. Edward Snowden used it to encrypt his communications with journalists. Many institutions use GnuPG because by using an open standard they can be sure that they will always be able to access their data. The 6 person development team is currently financed from a successful campaign in early 2015, regular donations from the Linux Foundation, Stripe, Facebook, and a few paid development projects. To ensure long-term stability the new campaign focuses on recurring donations and not one-time donations. Says lead developer Werner Koch: “We want to continue our work in the long term. But, we want to do so in such a way that our first loyalty is unambiguously to the general public. This means making sure that a majority of our funding comes from individual donors, and not corporations.” To highlight GnuPG's role in protecting data, user stories from 26 organizations including activist groups, news organizations, lawyers, and companies from all over the world have been collected. Their testimonials are presented in daily changing videos on the campaign site. About GNU Privacy Guard (GnuPG) Since 1997, GnuPG has allowed individuals and companies to encrypt and sign data and communication using the well-established and highly interoperable OpenPGP standard. It comes with state of the art cryptography and features a versatile key management system. GnuPG, also known as GPG or sometimes incorrectly as PGP, can be used standalone, but has all features needed for easy integration with other software. It is used as the core cryptography engine of a wealth of other applications: For example Thunderbird with Enigmail, Gpg4win, and GPGTools. Most operating systems use GnuPG's signing ability to protect system updates against malicious attempts to introduce backdoors. GnuPG is available free of charge, and comes with all source code to allow anyone to audit the software. About g10 Code GmbH g10 Code GmbH is the privately owned legal entity behind the GnuPG Project. They employ all developers and keep all profits for the development of GnuPG and related free software. ### Media contacts: Neal H.

The GnuPG Project is pleased to announce the availability of Libgcrypt version 1.7.8. This release fixes a local side-channel attack. Libgcrypt is a general purpose library of cryptographic building blocks. It is originally based on code used by GnuPG. It does not provide any implementation of OpenPGP or other protocols. Thorough understanding of applied cryptography is required to use Libgcrypt. Noteworthy changes in version 1.7.8 (2017-06-29) [C21/A1/R8] =================================== * Bug fixes: - Mitigate a flush+reload side-channel attack on RSA secret keys dubbed "Sliding right into disaster". For details see . [CVE-2017-7526] Note that this side-channel attack requires that the attacker can run arbitrary software on the hardware where the private RSA key is used. Allowing execute access to a box with private keys should be considered as a game over condition, anyway. Thus in practice there are easier ways to access the private keys than to mount this side-channel attack. However, on boxes with virtual machines this attack may be used by one VM to steal private keys from another VM.
