CVE-2015-1789 - Exploitable out-of-bounds read in X509_cmp_time
CVE-2015-1792 - CMS verify infinite loop with unknown hash function

Note that CMS was already disabled in LibreSSL.

Several other issues did not apply or were already fixed and one low
severity issue is under review.  For more information, see
https://www.openssl.org/news/secadv_20150611.txt

Thanks to the OpenSSL team for providing patches.

LibreSSL 2.1.7 and 2.2.0 released

We have released LibreSSL 2.2.0, which will be arriving in the
LibreSSL directory of your local OpenBSD mirror soon.

This release is the first from the OpenBSD 5.8 development tree and
features mainly on build system improvements and new OS support.

We have also released LibreSSL 2.1.7, which contains additional security
fixes.

  * AIX Support - thanks to Michael Felt

  * Cygwin Support - thanks to Corinna Vinschen

  * Refactored build macros, support packaging libtls independently.
    There are more pieces required to support building and using OpenSSL
    with libtls, but this is an initial start at providing an
    independent package for people to start hacking on.

  * Removal of OPENSSL_issetugid and all library getenv calls.
    Applications can and should no longer rely on environment variables
    for changing library behavior. OPENSSL_CONF/SSLEAY_CONF is still
    supported with the openssl(1) command.

  * libtls API and documentation additions

  * Various bug fixes and simplifications to libssl and libcrypto

  * Fixes for the following issues are integrated into LibreSSL 2.1.7
    and LibreSSL 2.2.0:
    - CVE-2015-1788 - Malformed ECParameters causes infinite loop

5.7 CDs delayed

Sorry, 5.7 CDs will be delayed because of an error at the production
plant.

We all hoped it would be resolved before release day, or at most a day
or so after.  It has dragged on.

First delay in nearly 20 years.  That is kind of crazy, isn't it.

Of course the online release is out like clockwork.

OpenBSD 5.7 Released

May 1, 2015.

We are pleased to announce the official release of OpenBSD 5.7.
This is our 37th release on CD-ROM (and 38th via FTP/HTTP).  We remain
proud of OpenBSD's record of more than ten years with only two remote
holes in the default install.

As in our previous releases, 5.7 provides significant improvements,
including new features, in nearly all areas of the system:

 - Improved hardware support, including:
    o New xhci(4) driver for USB 3.0 host controllers.
    o New umcs(4) driver for MosChip Semiconductor 78x0 USB multiport
      serial adapters.
    o New skgpio(4) driver for Soekris net6501 GPIO and LEDs.
    o New uslhcom(4) driver for Silicon Labs CP2110 USB HID based UART.
    o New nep(4) driver for Sun Neptune 10Gb Ethernet devices.
    o New iwm(4) driver for Intel 7260, 7265, and 3160 wifi cards.
    o The rtsx(4) driver now supports RTS5227 and RTL8411B card readers.
    o The bge(4) driver now supports jumbo frames on various additional
      BCM57xx chipsets.
    o The ciss(4) driver now supports HP Gen9 Smart Array/Smart HBA
      devices.
    o The mpi(4) and mfi(4) drivers now have mpsafe interrupt handlers
      running without the big lock.
    o The ppb(4) driver now supports PCI bridges that support
      subtractive decoding (fixes PCMCIA behind the ATI SB400 PCI
      bridge), and devices with 64-bit BARs behind PCI-PCI bridges as
      seen on SPARC T5-2 systems.
    o The puc(4) driver now supports Winchiphead CH382 devices.

tar/pax/cpio patch available

Patches are now available for 5.6 and 5.7 which fix security issues
in the combined tar, pax, and cpio program's handling of malicious
archives, as well as archives with large pax extension headers.

Our thanks to Daniel Cegielka for reporting this.

Note that the patches for 5.6 and 5.7 have several differences, so be
sure to download the correct version.

OpenBSD 5.7 errata 7, Apr 30, 2015:

tar/pax/cpio had multiple issues:
 * extracting a malicious archive could create files outside of the
   current directory without using pre-existing symlinks to 'escape',
   and could change the timestamps and modes on preexisting files

 * tar without -P would permit extraction of paths with ".." components

 * there was a buffer overflow in the handling of pax extension headers,

kernel patch available

Patches are now available for 5.6 and 5.7 which fix local security
issues in the kernel's handling of malformed ELF executables, which
could be used to panic the kernel or view some kernel memory.

for providing the basis for one of the changes.

OpenBSD 5.7 errata 6, Apr 30, 2015:

Missing validity checks in the kernel ELF loader meant malformed binaries
