|
<p>
|
|
A buffer overflow has been identified in the slc_add_reply()
|
|
function of netkit-telnetd client, where a large number of SLC commands
|
|
can overflow a fixed size buffer.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
Successful explotation would require a vulnerable user to connect
|
|
to an attacker-controlled host using telnet, potentially executing
|
|
arbitrary code with the permissions of the telnet user.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All netkit-telnetd users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/netkit-telnetd-0.17-r6"</code>
