Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200908-08
(ISC DHCP: dhcpd Denial of Service)

Christoph Biedl discovered that dhcpd does not properly handle certain
DHCP requests when configured both using 'dhcp-client-identifier' and
'hardware ethernet'.

Impact :

A remote attacker might send a specially crafted request to dhcpd,
possibly resulting in a Denial of Service (daemon crash).

Workaround :

There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose '>=net-misc/dhcp-3.1.2_p1'
