deadsimple BSD Security Advisories and Announcements

LibreSSL 2.3.2, 2.2.6, and 2.1.10 released

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

LibreSSL 2.2.6 and 2.1.10 contain a single change to deprecate use of
the SSL_OP_SINGLE_DH_USE flag. It is now enabled unconditionally.
Thanks to Antonio Sanso for the report.

LibreSSL 2.3.2, a snapshot release, contains the latest developments
from the OpenBSD 5.9 branch. It also contains ABI/API changes, which
will stabilize once OpenBSD 5.9 is completed. At that time, LibreSSL
2.3.x and 2.2.x will become the stable release branches, and we will
drop support for the 2.1.x branch.

LibreSSL 2.3.2 also has the following notable changes:

    * Changed format of LIBRESSL_VERSION_NUMBER to match that of

    * Added EVP_aead_chacha20_poly1305_ietf() which matches the AEAD
      construction introduced in RFC 7539, which is different than that
      already used in TLS with EVP_aead_chacha20_poly1305()

    * Avoid a potential undefined C99+ behavior due to shift overflow in
      AES_decrypt, reported by Pascal Cuoq <cuoq at>

    * More man pages converted from pod to mdoc format

    * Added COMODO RSA Certification Authority and QuoVadis
      root certificates to cert.pem

    * Removed Remhve "C=US, O=VeriSign, Inc., OU=Class 3 Public Primary
      Certification Authority"
      (serial 3c:91:31:cb:1f:f6:d0:1b:0e:9a:b8:d0:44:bf:12:be)
      root certificate from cert.pem

    * Added support for building nc(1) on Solaris

    * Fixed GCC 5.x+ preprocessor checks, reported by Ruslan Babayev

    * Improved console handling with openssl(1) on Windows

    * Ensure the network stack is enabled on Windows when running

    * Fixed incorrect TLS certificate loading by nc(1)

    * Added support for Solaris 11.3's getentropy(2) system call

    * Enabled support for using NetBSD 7.0's arc4random(3) implementation

    * Deprecated the SSL_OP_SINGLE_DH_USE flag, thanks to Antonio Sanso.

    * Fixes from OpenSSL 1.0.1q (already in earlier LibreSSL stable releases)
     - CVE-2015-3194 - NULL pointer dereference in client side certificate
     - CVE-2015-3195 - Memory leak in PKCS7 - not reachable from TLS/SSL

    * The following OpenSSL CVEs did not apply to LibreSSL
     - CVE-2015-3193 - Carry propagating bug in the x86_64 Montgomery
                       squaring procedure.
     - CVE-2015-3196 - Double free race condition of the identify hint


The LibreSSL project continues improvement of the codebase to reflect modern,
safe programming practices. We welcome feedback and improvements from the
broader community. Thanks to all of the contributors who helped make this
release possible.
