GLSA-200908-08 : ISC DHCP: dhcpd Denial of Service

medium Nessus Plugin ID 40633

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.

Solution

All ISC DHCP users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/dhcp-3.1.2_p1'
