+<define-tag moreinfo>
+<p>Fabian Baeumer, Marcus Brinkmann and Joerg Schwenk discovered that the
+SSH protocol is prone to a prefix truncation attack, known as the
+<q>Terrapin attack</q>. This attack allows a MITM attacker to effect a
+limited break of the integrity of the early encrypted SSH transport
+protocol by sending extra messages prior to the commencement of
+encryption, and deleting an equal number of consecutive messages
+immediately after encryption starts.</p>
+
+<p>Details can be found at <a href="https://terrapin-attack.com/">\
+https://terrapin-attack.com/</a>.</p>
+
+<p>For the oldstable distribution (bullseye), these problems have been fixed
+in version 0.74-1+deb11u1. This update includes a fix for
+<a href="https://security-tracker.debian.org/tracker/CVE-2021-36367">CVE-2021-36367</a>.</p>
+
+<p>For the stable distribution (bookworm), these problems have been fixed in
+version 0.78-2+deb12u1.</p>
+
+<p>We recommend that you upgrade your putty packages.</p>
