Subject: bug#68619: dhcp-client-service-type uses end-of-life dhclient
Date: Sat, 20 Jan 2024 19:44:44 +0100 [thread overview]
Message-ID: <3IU8CAI5QIGEI.2W06JXCLXMAYZ@8pit.net> (raw)
Hello,
I recently installed the Guix operating system and selected DHCP-based
network configuration in the installer. Today I noticed that the DHCP
client installed by default seems to be dhclient from ISC-DHCP. This is
problematic as this DHCP implementation has reached its end-of-life in
2022 [1]. This is also mentioned in the Guix package description.
The dhcp-client-service-type has a package configuration option, in
theory, allowing usage with other DHCP clients. Unfortunately, it seems
to require that the package provides /sbin/dhclient and I am not aware
of any package that has this executable. In general, it seems there
is no other DHCP client package available in Guix.
Therefore, I believe the course of action here would be to: (a) package
a different DHCP client (dhcpcd [2] may be a good candidate) and (b)
make sure that dhcp-client-service-type is compatible with this client
and uses it by default.
I would argue that this is an important issue, as a DHCP client
processes untrusted input from the local network and is thus subject to
potential security vulnerabilities.
Greetings,
Sören
