Adam Zabrocki reported a boundary error within the split_redraw()
function in the file split.c, possibly leading to a stack-based buffer
overflow.

<impact type="high">
<p>
A remote attacker could use a specially crafted resolved hostname to
execute arbitrary code with root privileges. However, it is required
that the attacker controls the DNS server used by the victim, and that
the "-p" (or "--split") command line option is used.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All mtr users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-analyzer/mtr-0.73-r1&quot;</code>
</resolution>
