|
|
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.

<resolution>

All mtr users should upgrade to the latest version:

|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-analyzer/mtr-0.73-r1"</code>
