0d0f3050-1f69-11e5-9ba9-d050996490d0 | ntp -- control message remote Denial of Service vulnerability
ntp.org reports:
Under limited and specific circumstances an attacker can send a
crafted packet to cause a vulnerable ntpd instance to crash.
This requires each of the following to be true:
- ntpd set up to allow for remote configuration (not
allowed by default), and
- knowledge of the configuration password, and
- access to a computer entrusted to perform remote
configuration.

591a706b-5cdc-11ea-9a0a-206a8a720317 | ntp -- Multiple vulnerabilities
nwtime.org reports:
Three ntp vulnerabilities, Depending on configuration, may have
little impact up to termination of the ntpd process.
NTP Bug 3610: Process_control() should exit earlier on short
packets. On systems that override the default and enable ntpdc
(mode 7) fuzz testing detected that a short packet will cause
ntpd to read uninitialized data.
NTP Bug 3596: An unauthenticated unmonitored ntpd is vulnerable
to attack on IPv4 with highly predictable transmit timestamps. An
off-path attacker who can query time from the victim's ntp which
receives time from an unauthenticated time source must be able to
send from a spoofed IPv4 address of upstream ntp server and and
the victim must be able to process a large number of packets with
the spoofed IPv4 address of the upstream server. After eight or
more successful attacks in a row the attacker can either modify
the victim's clock by a small amount or cause ntpd to terminate.
The attack is especially effective when unusually short poll
intervals have been configured.
NTP Bug 3592: The fix for https://bugs.ntp.org/3445 introduced
a bug such that a ntp can be prevented from initiating a time
volley to its peer resulting in a DoS.
All three NTP bugs may result in DoS or terimation of the ntp
daemon.

- Bug 1774 : Segfaults if cryptostats enabled when built
without OpenSSL
- Bug 1593 : ntpd abort in free() with logconfig syntax error
