+<define-tag description>LTS security update</define-tag>
+<define-tag moreinfo>
+<p>xrdp-sesman service in xrdp can be crashed by connecting over port 3350 and
+supplying a malicious payload. Once the xrdp-sesman process is dead, an
+unprivileged attacker on the server could then proceed to start their own
+imposter sesman service listening on port 3350. This will allow them to capture
+any user credentials that are submitted to XRDP and approve or reject arbitrary
+login credentials. For xorgxrdp sessions in particular, this allows an
+unauthorized user to hijack an existing session. This is a buffer overflow
+attack, so there may be a risk of arbitrary code execution as well.</p>
+
+<p>For Debian 9 stretch, this problem has been fixed in version
+0.9.1-9+deb9u4.</p>
+
+<p>We recommend that you upgrade your xrdp packages.</p>
