<description>
|
|
<p>The recv_and_process_client_pkt function in networking/ntpd.c in BusyBox
|
|
allows remote attackers to cause a Denial of Service (CPU and bandwidth
|
|
consumption) via a forged NTP packet, which triggers a communication
|
|
loop.

|
|
<impact type="normal">
|
|
<p>A remote attacker might send a specially crafted package to a machine
|
|
running BusyBox ntpd, possibly resulting in a Denial of Service
|
|
condition.

|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All BusyBox users should upgrade to the latest version:</p>

<code>
|

# emerge --sync
|
