+	<p>Importing an OpenPGP key having a preference list for AEAD algorithms
+	will lead to an array overflow and thus often to a crash or other
+	undefined behaviour.</p>
+
+	<p>Importing an arbitrary key can often easily be triggered by an attacker
+	and thus triggering this bug.  Exploiting the bug aside from crashes is
+	not trivial but likely possible for a dedicated attacker.  The major
+	hurdle for an attacker is that only every second byte is under their
+	control with every first byte having a fixed value of 0x04.</p>
