+	  <p>Vulnerability Details:
+	Sending malformed NOOP command causes crash in submission, submission-login or
+	lmtp service.
+
+Risk:
+	Remote attacker can keep submission-login service down, causing denial of
+	service attack. For lmtp the risk is neglible, as lmtp is usually behind a
+	trusted MTA.
+
+Steps to reproduce:
+	Send ``NOOP EE"FY`` to submission port, or similarly malformed command.</p>
+	  <p>Vulnerability Details:
+
+	Sending command followed by sufficient number of newlines triggers a
+	use-after-free bug that might crash submission-login, submission or
+	lmtp service.
+
+Risk:
+
+	Remote attacker can keep submission-login service down, causing denial
+	of service attack. For lmtp the risk is neglible, as lmtp is usually
+	behind a trusted MTA.
+
+Steps to reproduce:
+
+	This can be currently reproduced with ASAN or Valgrind. Reliable way to
+	crash has not yet been discovered.
+	</p>
+	<p>Vulnerability Details:
+	Sending mail with empty quoted localpart causes submission or lmtp component
+	to crash.
+
+Risk:
+	Malicious actor can cause denial of service to mail delivery by repeatedly
+	sending mails with bad sender or recipient address.
+
+Steps to reproduce:
+	Send mail with envelope sender or recipient as &lt;""@example.org&gt;.
+
+Workaround:
+	For submission there is no workaround, but triggering the bug requires valid
+	credentials.
+	For lmtp, one can implement sufficient filtering on MTA level to prevent mails
+	  with such addresses from ending up in LMTP delivery.</p>
