+  *) Prevent padding oracle in AES-NI CBC MAC check
+
+     A MITM attacker can use a padding oracle attack to decrypt traffic
+     when the connection uses an AES CBC cipher and the server support
+     AES-NI.
+
+     This issue was introduced as part of the fix for Lucky 13 padding
+     attack (CVE-2013-0169). The padding check was rewritten to be in
+     constant time by making sure that always the same bytes are read and
+     compared against either the MAC or padding bytes. But it no longer
+     checked that there was enough data to have both the MAC and padding
+     bytes.
+
+     This issue was reported by Juraj Somorovsky using TLS-Attacker.
+     (CVE-2016-2107)
+     [Kurt Roeckx]
+
+  *) Fix EVP_EncodeUpdate overflow
+
+     An overflow can occur in the EVP_EncodeUpdate() function which is used for
+     Base64 encoding of binary data. If an attacker is able to supply very large
+     amounts of input data then a length check can overflow resulting in a heap
+     corruption.
+
+     Internally to OpenSSL the EVP_EncodeUpdate() function is primarly used by
+     the PEM_write_bio* family of functions. These are mainly used within the
+     OpenSSL command line applications, so any application which processes data
+     from an untrusted source and outputs it as a PEM file should be considered
+     vulnerable to this issue. User applications that call these APIs directly
+     with large amounts of untrusted data may also be vulnerable.
+
+     This issue was reported by Guido Vranken.
+     (CVE-2016-2105)
+     [Matt Caswell]
+
+  *) Fix EVP_EncryptUpdate overflow
+
+     An overflow can occur in the EVP_EncryptUpdate() function. If an attacker
+     is able to supply very large amounts of input data after a previous call to
+     EVP_EncryptUpdate() with a partial block then a length check can overflow
+     resulting in a heap corruption. Following an analysis of all OpenSSL
+     internal usage of the EVP_EncryptUpdate() function all usage is one of two
+     forms. The first form is where the EVP_EncryptUpdate() call is known to be
+     the first called function after an EVP_EncryptInit(), and therefore that
+     specific call must be safe. The second form is where the length passed to
+     EVP_EncryptUpdate() can be seen from the code to be some small value and
+     therefore there is no possibility of an overflow. Since all instances are
+     one of these two forms, it is believed that there can be no overflows in
+     internal code due to this problem. It should be noted that
+     EVP_DecryptUpdate() can call EVP_EncryptUpdate() in certain code paths.
+     Also EVP_CipherUpdate() is a synonym for EVP_EncryptUpdate(). All instances
+     of these calls have also been analysed too and it is believed there are no
+     instances in internal usage where an overflow could occur.
+
+     This issue was reported by Guido Vranken.
+     (CVE-2016-2106)
+     [Matt Caswell]
+
+  *) Prevent ASN.1 BIO excessive memory allocation
+
+     When ASN.1 data is read from a BIO using functions such as d2i_CMS_bio()
+     a short invalid encoding can casuse allocation of large amounts of memory
+     potentially consuming excessive resources or exhausting memory.
+
+     Any application parsing untrusted data through d2i BIO functions is
+     affected. The memory based functions such as d2i_X509() are *not* affected.
+     Since the memory based functions are used by the TLS library, TLS
+     applications are not affected.
+
+     This issue was reported by Brian Carpenter.
+     (CVE-2016-2109)
+     [Stephen Henson]
+
+  *) EBCDIC overread
+
+     ASN1 Strings that are over 1024 bytes can cause an overread in applications
+     using the X509_NAME_oneline() function on EBCDIC systems. This could result
+     in arbitrary stack data being returned in the buffer.
+
+     This issue was reported by Guido Vranken.
+     (CVE-2016-2176)
+     [Matt Caswell]
+
+  *) Modify behavior of ALPN to invoke callback after SNI/servername
+     callback, such that updates to the SSL_CTX affect ALPN.
+     [Todd Short]
+
   *) Remove LOW from the DEFAULT cipher list.  This removes singles DES from the
      default.
