+	<blockquote cite="INSERT URL HERE">
+	  <p>AIDE before 0.17.4 allows local users to obtain root privileges
+	     via crafted file metadata (such as XFS extended attributes or
+	     tmpfs ACLs), because of a heap-based buffer overflow.</p>
+	  <p>Aide uses a fixed size (16k bytes) for the return buffer in
+	     encode_base64/decode_base64 functions. This results in a segfault
+	     if aide processes a file with too large extended attribute value
+	     or ACL.</p>
