Description Peter Vrabec 2007-10-23 10:17:33 UTC 
dhcp should be ported to use NSS library for cryptography.
See the tracking bug for details and links on how it could be done.
Comment 1 David Cantrell 2007-10-23 14:45:29 UTC 
dhcp (both dhcpd and dhclient and dhcrelay) does not have any built-in
authentication code.  dhcpd links with with libldap for sites wanting to store
DHCP server configuration data in an LDAP directory, so any authentication that
happens around DHCP is for connecting to the LDAP server and that's all handled
by OpenLDAP.
Comment 2 Tomas Mraz 2007-10-23 14:55:36 UTC 
It contains built in MD5 and HMAC-MD5 algorithms. If they are used in security
relevant context they should be replaced with calls to NSS.
Comment 3 David Cantrell 2007-10-23 15:03:41 UTC 
Oh right, my bad.  For the dnssec stuff.

Comment 6 David Cantrell 2009-09-21 20:25:09 UTC 
I've attached two patches I started to convert dhcp to the NSS libraries.  Both patches are incomplete, but might be a starting place.
Comment 7 Jiri Popelka 2012-08-17 14:41:10 UTC 
ISC DHCP hasn't used the code mentioned in comment #2 since version 4.2.0, see bug #849166.

Closing therefore.
