+	    The old versions of <code>CGI::Cookie.parse</code> applied
+	    URL decoding to cookie names. An attacker could exploit
+	    this vulnerability to spoof security prefixes in cookie
+	    names, which may be able to trick a vulnerable
+	    application.
+	  </p>
+	  <p>
+	    By this fix, <code>CGI::Cookie.parse</code> no longer
+	    decodes cookie names. Note that this is an incompatibility
+	    if cookie names that you are using include
+	    non-alphanumeric characters that are URL-encoded.
