An integer overflow can occur in NTP-dev.4.3.70 leading to an out-of-bounds
memory copy operation when processing a specially crafted private mode
packet. The crafted packet needs to have the correct message authentication
code and a valid timestamp. When processed by the NTP daemon, it leads to
an immediate crash.
