+  <description>
+    <p>
+    Buffer overflow vulnerabilities in the slc_add_reply() and
+    env_opt_add() functions have been discovered by Gael Delalleau in the
+    telnet client in Heimdal.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    Successful exploitation would require a vulnerable user to connect
+    to an attacker-controlled host using the telnet client, potentially
+    executing arbitrary code with the permissions of the user running the
+    application.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Heimdal users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=app-crypt/heimdal-0.6.4&quot;</code>
