SSL defeated in IE and Konqueror

"A chain is formed when an intermediate certificate is trusted between server and client. Supposedly, the intermediate is accepted only if it's signed by the certificate authority as safe for the purpose. If it's merely signed by another certificate's key, it ought not to be trusted, or at least the user should be warned. Unfortunately, due to a preposterous security engineering oversight, IE and Konqueror don't bother to check this, so if a tricky site owner signs an intermediate cert with another valid cert, users will be none the wiser."
