[bug#70022] [PATCH 0/2] Binary Installation: Add more distros.

[Denis 'GNUtoo' Carikli]

Hi, this patchset documents the status of Guix packages in Trisquel and
Parabola that I also both use.

For Trisquel the guix package probably comes from some upstram
distribution.

For Parabola, the package comes from AUR, the Arch Linux User repository,
which is a community repository for Arch Linux where anyone can
contribute/maintain packages. I added that package in Parabola, and the
guix-installer packages was made from scratch by me.

As for the list of distributions that have Guix packages, we can find more at
https://repology.org/project/guix/versions but unfortunately I'm not familiar
enough with the other ones (like Nix/NixOS, Alpine, etc) yet to confidently
add instructions to install the guix package.

More distros having guix packages can be found at:

[bug#70022] [PATCH 0/2] Binary Installation: Add more distros.

[pelzflorian (Florian Pelz)]

Hi Denis.  This is in principle a great improvement, however note that
recently (4th March or so) a local privilege escalation vulnerability in
guix-daemon was discovered
<https://guix.gnu.org/en/blog/2024/fixed-output-derivation-sandbox-bypass-cve-2024-27297/>
and many distros have not fixed it yet, such as AUR and therefore your
Parabola pcr package or Debian’s long-term releases, which Debian’s guix
packager complained about
<https://security-tracker.debian.org/tracker/CVE-2024-27297>.

Perhaps we should think about how and where we can also instruct users
to upgrade their daemon in a timely manner.  This will be different for
guix packages (that configure a vulnerable daemon systemd service) and
for guix-install (where it is enough to follow the guix pull news file,
if the admin actually uses guix pull themself and can see the news).

Otherwise LGTM.

Regards,
Florian

[-- Attachment #1: Type: text/plain, Size: 521 bytes --]

Hi,

About the local privilege escalation, is there any hints on how to fix
it beside updating guix with 'guix pull'? 

For instance were there distributions that somehow backported the
patch, in order not to have a security issue when you do 'apt install
guix' or pamcan -S guix for instance?

I'm asking because while I'm not the AUR maintainer of the 'guix'
package, I know PKGBUILDs well enough to be able to send a patch if I
find the time (and also update the Parabola package along the way).

Denis.

Thinking more about it, I guess the Binary Installation documentation
should inform that one can install from distribution packages or from
guix-install.sh, depending on who should be responsible for security
updates.

Thank you for your offer.  Following hyperlinks from
<https://security-tracker.debian.org/tracker/CVE-2024-27297>, I find on
<https://udd.debian.org/patches.cgi?src=guix&version=1.4.0-6> security
patches that Vagrant cherry-picked from the Guix commits that address
the vulnerability.  Similar to how Guix often takes patches from Debian,
you could take the patches from Guix too or indirectly from Debian.

Regards,
Florian

Not sure if that'd be clearer, but an alternative would be:

For Debian or derivatives such as Ubuntu and Trisquel, call:

I find that less 'or'y, but that's probably a matter of taste :-).

I think I'd go with "If you are running Parabola [...]" (dropping the
"And" which seems extraneous and the 'you are' -> 'you're' contraction).
