Bugs: #275231
ID: 200908-08
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
dhcpd as included in the ISC DHCP implementation does not properly
handle special conditions, leading to a Denial of Service.
Background
==========
ISC DHCP is the reference implementation of the Dynamic Host
Configuration Protocol as specified in RFC 2131.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/dhcp = 3.1.2_p1
Description
===========
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.
Resolution
==========
All ISC DHCP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose =net-misc/dhcp-3.1.2_p1
References
==========
