Affected Packages

Package Vulnerable Unaffected ------------ ------------ ------------ net-misc/ntp < 4.2.8_p16 >= 4.2.8_p16

Impact

The first four of these CVEs affect a function in libntp that is only used by ntpq, but not by ntpd.
The last CVE affects the driver for a hardware clock (GPS receiver), so ntpd might be vulnerable to manipulated devices of that type, but not to remote attacks.

Workaround

There is no known workaround at this time.
