+Emacs message-mode uses certain text strings to indicate how to attach\r
+files to outgoing mail.  If these are present in the text of an email,\r
+and a user is tricked into replying to the message, the user’s files\r
+could be exposed.\r
+---\r
+\r
+To demonstrate this, open a reply to this message then remove the\r
+exclamation marks after the hash marks below.  Create a file in your\r
+home directory called passwd.  Then press C-u M-x mml-preview.  A\r
+(possibly base64-encoded) version of your ~/passwd file will replace\r
+the following lines:\r
+\r
+<#!part type="application/octet-stream" filename="~/passwd"\r
+disposition=attachment description=foo>\r
+<#!/part>\r
+\r
+It works equally well (and more dangerously) with /etc/passwd, but I\r
+didn't use that filename here to avoid the danger of someone\r
+accidentally attaching their /etc/passwd to a reply in this thread!\r
