+  *) 0-byte record padding oracle
+
+     If an application encounters a fatal protocol error and then calls
+     SSL_shutdown() twice (once to send a close_notify, and once to receive one)
+     then OpenSSL can respond differently to the calling application if a 0 byte
+     record is received with invalid padding compared to if a 0 byte record is
+     received with an invalid MAC. If the application then behaves differently
+     based on that in a way that is detectable to the remote peer, then this
+     amounts to a padding oracle that could be used to decrypt data.
+
+     In order for this to be exploitable "non-stitched" ciphersuites must be in
+     use. Stitched ciphersuites are optimised implementations of certain
+     commonly used ciphersuites. Also the application must call SSL_shutdown()
+     twice even if a protocol error has occurred (applications should not do
+     this but some do anyway).
+
+     This issue was discovered by Juraj Somorovsky, Robert Merget and Nimrod
+     Aviram, with additional investigation by Steven Collison and Andrew
+     Hourselt. It was reported to OpenSSL on 10th December 2018.
