<p>Heimdal is a free implementation of Kerberos 5.</p>
<p>A boundary error in the "encrypt_keyid()" function in
appl/telnet/libtelnet/encrypt.c of the telnet daemon and client could
cause a buffer overflow.
<impact type="high">
<p>An unauthenticated remote attacker may be able to execute arbitrary code
with the privileges of the user running the telnet daemon or client, or
cause Denial of Service.
<p>There is no known workaround at this time.</p>
<p>All Heimdal users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=app-crypt/heimdal-1.5.1-r1"
