+	<h1>Problem Description:</h1>
+	<p>Insufficient validation of environment variables in the
+	telnet client supplied in FreeBSD can lead to stack-based
+	buffer overflows. A stack- based overflow is present in the
+	handling of environment variables when connecting via the
+	telnet client to remote telnet servers.</p>
+	<p>This issue only affects the telnet client. Inbound telnet
+	sessions to telnetd(8) are not affected by this issue.</p>
+	<h1>Impact:</h1>
+	<p>These buffer overflows may be triggered when connecting
+	to a malicious server, or by an active attacker in the
+	network path between the client and server. Specially crafted
+	TELNET command sequences may cause the execution of arbitrary
+	code with the privileges of the user invoking telnet(1).</p>
