+	  <p>pngcheck versions 3.0.0 and earlier have a pair of buffer-overrun
+	    bugs related to the sPLT and PPLT chunks (the latter is a MNG-only
+	    chunk, but it gets noticed even in PNG files if the -s option is used).
+	    Both bugs are fixed in version 3.0.1, released on 24 January 2021.
+	    Again, while all known vulnerabilities are fixed in this version,
+	    the code is quite crufty, so it would be safest to assume there are
+	    still some problems hidden in there. As always, use at your own risk.</p>
