Description Sebastian Krahmer 2016-08-03 13:49:22 UTC

Quoting from OSS-sec:

Miroslav Lichvar of Red Hat reported a flaw in busybox's NTP
implementation:

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.
