+ <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 "&gt;=app-crypt/heimdal-0.6.4"</code>
