+Subject: [PATCH] Do not ignore empty associated data with AES-SIV mode
+
+The AES-SIV mode allows for multiple associated data items
+authenticated separately with any of these being 0 length.
+
+The provided implementation ignores such empty associated data
+which is incorrect in regards to the RFC 5297 and is also
+a security issue because such empty associated data then become
+unauthenticated if an application expects to authenticate them.

+Subject: [PATCH] Fix DH_check() excessive time with over sized modulus
+
+The DH_check() function checks numerous aspects of the key or parameters
+that have been supplied. Some of those checks use the supplied modulus
+value even if it is excessively large.
+
+There is already a maximum DH modulus size (10,000 bits) over which
+OpenSSL will not generate or derive keys. DH_check() will however still
+perform various tests for validity on such a large modulus. We introduce a
+new maximum (32,768) over which DH_check() will just fail.
+
+An application that calls DH_check() and supplies a key or parameters
+obtained from an untrusted source could be vulnerable to a Denial of
+Service attack.
+
+The function DH_check() is itself called by a number of other OpenSSL
+functions. An application calling any of those other functions may
+similarly be affected. The other functions affected by this are
+DH_check_ex() and EVP_PKEY_param_check().
