<description>
<p>
Nico Golde reported a stack-based buffer overflow when processing a MSN
packet with a UBX command containing a large UBX payload length field.
</p>

<impact type="normal">
<p>
A remote attacker could send a specially crafted message, possibly
resulting in the execution of arbitrary code.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
Since TMSNC is no longer maintained, we recommend that users unmerge
the vulnerable package and switch to another console-based MSN client
such as CenterIM or Pebrot:
</p>
<code>
# emerge --unmerge &quot;net-im/tmsnc&quot;</code>
