+	<p>The cURL project reports:</p>
+	<blockquote cite="https://curl.haxx.se/docs/adv_20171023.html">
+	  <p>libcurl contains a buffer overrun flaw in the IMAP handler.<br/>
+	    An IMAP FETCH response line indicates the size of the returned data,
+	    in number of bytes. When that response says the data is zero bytes,
+	    libcurl would pass on that (non-existing) data with a pointer and
+	    the size (zero) to the deliver-data function.<br/>
+	    libcurl's deliver-data function treats zero as a magic number and
+	    invokes strlen() on the data to figure out the length. The strlen()
+	    is called on a heap based buffer that might not be zero terminated
+	    so libcurl might read beyond the end of it into whatever memory lies
+	    after (or just crash) and then deliver that to the application as if
+	    it was actually downloaded.</p>
