OpenBSD 5.9 Errata for OCSP available

This errata fixes several issues in the OCSP code that could result in
the incorrect generation and parsing of OCSP requests. This remediates
a lack of error checking on time parsing in these functions, and
ensures that only
GENERALIZEDTIME formats are accepted for OCSP, as per RFC 6960.

Issues reported, and fixes provided by Kazuki Yamaguchi <k <at> rhe.jp>
and Kinichiro Inoguchi <kinichiro.inoguchi <at> gmail.com>

Patches for OpenBSD 5.9 are available at:
http://ftp.openbsd.org/pub/OpenBSD/patches/5.9/common/012_crypto.patch.sig

and have been committed to -current.

Portable LibreSSL releases will appear shortly.

libcrypto patch available for DSA security issue


Fixes are available to correct a problem that prevents the DSA signing
algorithm from running in constant time even if the flag
BN_FLG_CONSTTIME is set. 

This issue was reported by Cesar Pereida (Aalto University), Billy
Brumley (Tampere University of Technology), and Yuval Yarom (The
University of Adelaide and NICTA). The fix was developed by Cesar
Pereida.

Patches are available for 5.8 and 5.9 at:

http://ftp.openbsd.org/pub/OpenBSD/patches/5.8/common/017_crypto.patch.sig
http://ftp.openbsd.org/pub/OpenBSD/patches/5.8/common/011_crypto.patch.sig

and have been commmitted to -current. 

Portably LibreSSL releases will appear shortly.

LibreSSL 2.4.0/2.3.5/2.2.8 Released

We have released a first development snapshot of LibreSSL 2.4.0 along
with two stable builds, 2.3.5 and 2.2.8. These should be arriving in
the LibreSSL directory of your local OpenBSD mirror soon.

The 2.3.5 and 2.2.8 releases contain a reliability fix, correcting an
error when parsing certain ASN.1 elements over 16k in size.

The 2.4.0 release contains the following additional changes:

    * Implemented the IETF ChaCha20-Poly1305 cipher suites.

    * Changed default EVP_aead_chacha20_poly1305() implementation to the
      IETF version, which is now the default.

    * Many improvements to the CMake build infrastructure, including
      Solaris, mingw-w64, Cygwin, and HP-UX support. Thanks to Kinichiro
      Inoguchi for this work.

    * Reworked error handling in libtls so that configuration errors are
      more visible.

    * Added missing error handling around bn_wexpand() calls.

    * Added explicit_bzero calls for freed ASN.1 objects.

    * Fixed X509_*set_object functions to return 0 on allocation failure.

    * Fixed password prompts from openssl(1) to properly handle ^C.

    * Deprecated internal use of EVP_[Cipher|Encrypt|Decrypt]_Final.

OpenNTPD 6.0p1 available

OpenNTPD 6.0p1 has just been released. It will be available from the mirrors
listed at http://www.openntpd.org/ shortly.

OpenNTPD is a FREE, secure, and easy to use implementation of the Network Time
Protocol. It provides the ability to sync the local clock to remote NTP servers
and can act as NTP server itself, redistributing the local clock.

Changes since OpenNTPD 5.9p1
============================

    * Fixed a link failure on older Linux distributions and a build
      failure on FreeBSD.
    * Set MOD_MAXERROR to avoid unsynced time status when using
      ntp_adjtime.
    * Fixed HTTP Timestamp header parsing to use strptime in a more
      portable fashion.
    * Hardened TLS for ntpd constraints, enabling server name
      verification. Thanks to Luis M. Merino.

The libtls library, as shipped with LibreSSL 2.3.2 or later, is
required to use the HTTPS constraint feature, though it is not
required to use OpenNTPD.

For detailed changes, see the changes either in the OpenBSD CVS repository or
the GitHub mirror.

Checksums:
==========

SHA256 (openntpd-6.0p1.tar.gz) = b1ab80094788912adb12b33cb1f251cc58db39294c1b5c6376972f5f7ba577e8

libcrypto errata update

Patches for OpenBSD are available. Updated LibreSSL-portable releases
will be available later.

libcrypto errata

OpenSSL announced several issues today that also affect LibreSSL.

- Memory corruption in the ASN.1 encoder (CVE-2016-2108)
- Padding oracle in AES-NI CBC MAC check (CVE-2016-2107)
- EVP_EncodeUpdate overflow (CVE-2016-2105)
- EVP_EncryptUpdate overflow (CVE-2016-2106)
- ASN.1 BIO excessive memory allocation (CVE-2016-2109)

Thanks to OpenSSL for providing information and patches.

OpenNTPD 5.9p1 released

OpenNTPD 5.9p1 has just been released. t will be available from the
mirrors listed at http://www.openntpd.org/ shortly.

OpenNTPD is a FREE, secure, and easy to use implementation of the
Network Time Protocol. It provides the ability to sync the local clock
to remote NTP servers and can act as NTP server itself, redistributing
the local clock.

Changes since OpenNTPD 5.7p4
============================
* When a single "constraint" is specified, try all returned addresses
  until one succeeds, rather than the first returned address.
* Relaxed the constraint error margin to be proportional to the number
  of NTP peers, avoid constant reconnections when there is a bad NTP
  peer.
* Removed disabled hotplug sensor support.
* Added support for detecting crashes in constraint subprocesses.
* Moved the execution of constraints from the ntp process to the
  parent process, allowing for better privilege separation since the
  ntp process can be further restricted.
* Added pledge(2) support.
* Updated to require LibreSSL 2.3.2 or greater.
* Fixed high CPU usage when the network is down.
* Fixed various memory leaks.
* Switched to RMS for jitter calculations.
* Unified logging functions with other OpenBSD base programs.

OpenNTPD portable-specific changes:

* Added support for syncing time with the Realtime Clock (RTC) on OSes
