+	  <h5>Issue 1:</h5>
+	  <p>
+	    Users are always granted permissions to cd into a directory.  The
+	    check for whether execute is present on directories is a de-facto
+	    no-op.  This cannot be mitigated without upgrading.  Even setting
+	    an explicit "deny - execute" NFSv4 ACE will be bypassed.
+	  </p>
+	  <h5>Issue 2:</h5>
+	  <p>
+	    All ACEs for the owner_group (group@) and regular groups
+	    (group:&lt;foo&gt;) are granted the current user.  This means that
+	    POSIX mode 770 is de-facto 777, and the below ACL is also de-facto
+	    777 because the groupmember check for builtin_administrators
+	    returns True.
