+ <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>
