The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-201001-01
(NTP: Denial of Service)
Robin Park and Dmitri Vinokurov discovered that ntp_request.c in ntpd
does not handle MODE_PRIVATE packets correctly, causing a continuous
exchange of MODE_PRIVATE error responses between two NTP daemons or
causing high CPU load on a single host.
A remote, unauthenticated attacker could send a specially crafted
MODE_PRIVATE packet, allowing for a Denial of Service condition (CPU
and bandwidth consumption).
There is no known workaround at this time.
