<description>
|
|
<p>The ipconfig utility in klibc writes DHCP options to
|
|
/tmp/net-$DEVICE.conf, and this file is later sourced by other scripts to
|
|
get defined variables. The options written to this file are not properly
|
|
escaped.
|
|
</p>

</description>
|
|
<impact type="normal">
|
|
<p>A remote attacker could send a specially crafted DHCP reply, which could
|
|
execute arbitrary shell code with the privileges of any process which
|
|
sources DHCP options.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All klibc users should upgrade to the latest version:</p>
|

<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/klibc-1.5.25"

</code>
