+	<h1>Problem Description:</h1>
+	<p>zlib through 1.2.12 has a heap-based buffer over-read or buffer
+	overflow in inflate in inflate.c via a large gzip header extra
+	field.</p>
+	<h1>Impact:</h1>
+	<p>Applications that call inflateGetHeader may be vulnerable to a
+	buffer overflow.  Note that inflateGetHeader is not used by anything
+	in the FreeBSD base system, but may be used by third party
+	software.</p>
