+	<p>Simon Tatham reports:</p>
+	<blockquote cite="https://lists.tartarus.org/pipermail/putty-announce/2019/000028.html">
+	  <p>Vulnerabilities fixed in this release include:</p>
+	  <ul>
+	    <li>A malicious SSH-1 server could trigger a buffer overrun by sending
+	      extremely short RSA keys, or certain bad packet length fields.
+	      Either of these could happen before host key verification, so even
+	      if you trust the server you *intended* to connect to, you would
+	      still be at risk.
+	    <br/>
+	      (However, the SSH-1 protocol is obsolete, and recent versions of
+	      PuTTY do not try it by default, so you are only at risk if you work
+	      with old servers and have explicitly configured SSH-1.)</li>
+	    <li>If a malicious process found a way to impersonate Pageant, then it
+	      could cause an integer overflow in any of the SSH client tools
+	      (PuTTY, Plink, PSCP, PSFTP) which accessed the malicious Pageant.</li>
+	  </ul>
+	  <p>Other security-related bug fixes include:</p>
+	  <ul>
+	    <li>The 'trust sigil' system introduced in PuTTY 0.71 to protect
+	      against server spoofing attacks had multiple bugs. Trust sigils
+	      were not turned off after login in the SSH-1 and Rlogin protocols,
+	      and not turned back on if you used the Restart Session command.
+	      Both are now fixed.</li>
+	  </ul>
