openntpd/busybox: denial of service
| Package(s): | openntpd busybox |
CVE #(s): | CVE-2016-6301
|
| Created: | August 9, 2016 |
Updated: | January 2, 2017 |
| Description: |
From the Mageia advisory:
The busybox NTP implementation doesn't check the NTP mode of packets
received on the server port and responds to any packet with the right
size. This includes responses from another NTP server. An attacker can
send a packet with a spoofed source address in order to create an infinite
loop of responses between two busybox NTP servers. Adding more packets to
the loop increases the traffic between the servers until one of them has a
fully loaded CPU and/or network. |
