+
+  *) 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.
+     (CVE-2019-1559)
+     [Matt Caswell]
+
+  *) Move strictness check from EVP_PKEY_asn1_new() to EVP_PKEY_asn1_add0().
+     [Richard Levitte]

-# CA - wrapper around ca to make it easier to use ... basically ca requires
-#      some setup stuff to be done before you can use it and this makes
-#      things easier between now and when Eric is convinced to fix it :-)
-#
-# CA -newca ... will setup the right stuff
-# CA -newreq[-nodes] ... will generate a certificate request 
-# CA -sign ... will sign the generated request and output 
-#
-# At the end of that grab newreq.pem and newcert.pem (one has the key 
-# and the other the certificate) and cat them together and that is what
-# you want/need ... I'll make even this a little cleaner later.
-#
-#
-# 12-Jan-96 tjh    Added more things ... including CA -signcert which
-#                  converts a certificate to a request and then signs it.
-# 10-Jan-96 eay    Fixed a few more bugs and added the SSLEAY_CONFIG
-#		   environment variable so this can be driven from
-#		   a script.
-# 25-Jul-96 eay    Cleaned up filenames some more.
-# 11-Jun-96 eay    Fixed a few filename missmatches.
-# 03-May-96 eay    Modified to use 'ssleay cmd' instead of 'cmd'.
-# 18-Apr-96 tjh    Original hacking
-#
-# Tim Hudson
-# tjh@cryptsoft.com
-#
-
-# 27-Apr-98 snh    Translation into perl, fix existing CA bug.
