  Changes between 1.1.0b and 1.1.0c [xx XXX xxxx]
 
+  *) ChaCha20/Poly1305 heap-buffer-overflow
+
+     TLS connections using *-CHACHA20-POLY1305 ciphersuites are susceptible to
+     a DoS attack by corrupting larger payloads. This can result in an OpenSSL
+     crash. This issue is not considered to be exploitable beyond a DoS.
+
+     This issue was reported to OpenSSL by Robert Święcki (Google Security Team)
+     (CVE-2016-7054)
+     [Richard Levitte]
+
+  *) CMS Null dereference
+
+     Applications parsing invalid CMS structures can crash with a NULL pointer
+     dereference. This is caused by a bug in the handling of the ASN.1 CHOICE
+     type in OpenSSL 1.1.0 which can result in a NULL value being passed to the
+     structure callback if an attempt is made to free certain invalid encodings.
+     Only CHOICE structures using a callback which do not handle NULL value are
+     affected.
+
+     This issue was reported to OpenSSL by Tyler Nighswander of ForAllSecure.
+     (CVE-2016-7053)
+     [Stephen Henson]
+
+  *) Montgomery multiplication may produce incorrect results
+
+     There is a carry propagating bug in the Broadwell-specific Montgomery
+     multiplication procedure that handles input lengths divisible by, but
+     longer than 256 bits. Analysis suggests that attacks against RSA, DSA
+     and DH private keys are impossible. This is because the subroutine in
+     question is not used in operations with the private key itself and an input
+     of the attacker's direct choice. Otherwise the bug can manifest itself as
+     transient authentication and key negotiation failures or reproducible
+     erroneous outcome of public-key operations with specially crafted input.
+     Among EC algorithms only Brainpool P-512 curves are affected and one
+     presumably can attack ECDH key negotiation. Impact was not analyzed in
+     detail, because pre-requisites for attack are considered unlikely. Namely
+     multiple clients have to choose the curve in question and the server has to
+     share the private key among them, neither of which is default behaviour.
+     Even then only clients that chose the curve will be affected.
+
+     This issue was publicly reported as transient failures and was not
+     initially recognized as a security issue. Thanks to Richard Morgan for
+     providing reproducible case.
+     (CVE-2016-7055)
+     [Andy Polyakov]
+
   *) Removed automatic addition of RPATH in shared libraries and executables,
      as this was a remainder from OpenSSL 1.0.x and isn't needed any more.
      [Richard Levitte]
