+  *) Alternate chains certificate forgery
+
+     During certificate verfification, OpenSSL will attempt to find an
+     alternative certificate chain if the first attempt to build such a chain
+     fails. An error in the implementation of this logic can mean that an
+     attacker could cause certain checks on untrusted certificates to be
+     bypassed, such as the CA flag, enabling them to use a valid leaf
+     certificate to act as a CA and "issue" an invalid certificate.
+
+     This issue was reported to OpenSSL by Adam Langley/David Benjamin
+     (Google/BoringSSL).

+  *) Fix HMAC ABI incompatibility. The previous version introduced an ABI
+     incompatibility in the handling of HMAC. The previous ABI has now been
+     restored.
