+		<p>
+			When building anonymizing circuits to or from an onion
+			service with 'lite' vanguards (the default) enabled, the
+			circuit manager code would build the circuits with one
+			hop too few.
+		</p>
+		<p>
+			When 'full' vanguards are enabled, some circuits are
+			supposed to be built with an extra hop to minimize the
+			linkability of the guard nodes. In some circumstances,
+			the circuit manager would build circuits with one hop
+			too few, making it easier for an adversary to discover
+			the L2 and L3 guards of the affected clients and
+			services.
