+ <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 <""@example.org>.
+
+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>
