Hi Guix,

I was wanting to check on some executable files in the store,
and happened to see some executable .png files ;-/

I suspect they came in when I was playing with icecat
and let it load a "theme", but I am not sure some didn't
also happen trying to get firefox radio buttons to work ;-/

Anyway, does anyone else get 555 permissions on files like these?
These are all *.png files with 555 permissons, but I trimmed back to see common prefixes.
Obviously the moka-con-theme was most of it, but also faba and docbook look iffy.

Is this zero-day stuff with a nasty somewhere, waiting for referencing by another nasty, or am I being paranoid?
What is the safe way to detoxify this mess? I know I shouldn't directly chmod anything in store, right?

The icecat discussion got moved to mozilla, but in case someone else did whatever I did,
I thought I'd post a heads-up here.
I'll try to cc Mark :)

Maybe I’m missing something, but none of the above are PNGs.
Most of them are executables, others are directories, so having them
executable is expected.

Did I misunderstand?

I am not sure to understand the issue but for example:

find /gnu/store/ -type f -perm /111 -iname '*.png' -print

returns this file:

/gnu/store/xj7kn8vw1nkcg7qpl3491b831p88i9wn-python-coverage-4.5.3/lib/python3.7/site-packages/coverage/htmlfiles/keybd_open.png

Bengt, Ricardo,

I see similar results here with ‘guix install moka-icon-theme’,
and I'm sure the rest of my (and everyone's) store is full of
misperm'd files too. It's kind of generally known.

This seems to be particularly common in Meson packages: for some
reason, Meson installs everything as executable by default.

What's the threat model there? Respectfully, I think you might
be, but maybe I'm naive…

Otherwise I consider this a merely cosmetic issue, but we still
welcome fixes for those!

Checking whether Meson behaves differently on other distributions
would be a good start.

Bengt's clever pipeline tallies the number of executable *png
files in each top-level store directory. It does not include
directories.

It's true that the '*png' above should be replaced with '*.png',
but these /bin files are just the very noisy outliers.

The meat is in:

i.e. 34143 executable '*png' files in that directory alone.

Kind regards,

Certainly not. Unless you ran icecat as root, it would not have
sufficient permissions to modify /gnu/store. Installing a theme or
addon in IceCat, or changing its configuration, modifies files in your
~/.mozilla, not /gnu/store.

I looked at docbook-xsl-1.79.1, since I happen to have it installed on
my system. Some of the *.png files are incorrectly given executable
permissions within the upstream source tarball itself. I guess it's
probably the same issue with moka-icon-theme and faba-icon-theme, since
I don't see anything in our package code that would have done it.

Most of the entries in your list that end with "png" but not ".png" are
actually programs whose name ends with "png", so they *should* be
executable. The files in /gnu/store/.links that end with "png" are just
random chance, because the file names themselves are hashes.

I think you're being paranoid in this case. I don't see anything here
to be concerned about, just some minor sloppiness by 3 upstreams.

Toggle quote (2 lines)
> What is the safe way to detoxify this mess?

The proper solution is to send bug reports to the upstream developers of
docbook-xsl, faba-icon-theme, and moka-icon-theme, asking them to fix
the permissions of the *.png files in their source tarballs.

Right, *never* modify files in /gnu/store directly.

Yes, d'oh ;-) I was writing the "PS." in my reply to Ricardo probably
while you were writing this :) There I extracted some
guix build -S tarball content and showed that that was the perm source.

Yes, I found the bad perms in the tarball likewise.

Yeah, I realized. Could have done a cleaner job, but I was also curious
how many legit executables ended in png.

IIRC I did read of jpeg images being used to obfuscate call-home info
in some tricky malware, so anomalies in the same kind of file triggered
the question of whether it could be accidentally on purpose ;-/

That I haven't done. Is there a standard way to do it?
"guix show moka-icon-theme" tells me homepage, but it would be nice
to have a guix show --verbose that would show bug reporting info :)

It would be nice, but it would also be an enormous amount of work.
First we'd need to devise a way to represent that information, and then
we'd need to add it to each of our 10K+ packages. It would also be an
additional job to do when adding new packages. I'm not sure it's worth
all that work. We already record the home page, and from there it's
usually not much work to find how to report bugs. In cases where it
_is_ difficult to find out how to report bugs, that's arguably a problem
that should be fixed upstream.

What do you think?

Mark

Also, we should not encourage people to report bugs upstream directly. We have to evaluate whether the bug is on our side or theirs first to not drown them in useless bug reports :)

Hm, this seems like it could be important for good relations with upstream?
Should there be an official _distilled and filtered-for-upstream_
git bug repo that guix developers populate and upstream devs
(and anyone) can pull and grep the log of for their projects?
I could imagine (hallucinate ? :) some benfits:
1. First of all, we can all determine easily if there has been
an "official" report from guix to upstream, to avoid even bothering
guix developers.
2. If upstream devs know reports have been considered important enough
by guix developers to be put in the repo, they might pay more attention :)
There is a lot of tl;dr discussion in many bug-reporting logs, so upstream
would probably appreciate having curated reports.
3. The log would be a record. Commit hashes would become precise references.
4. To keep the main bug info stream clear of speculative chatty stuff
(though this sometimes contains critical clues, and belongs somewhere)
the repo could contain (per major upstream?) files for commentary or
miscellaneous that guix devs might want to pass on, but not clutter
the main report with. Of course urls into bugzilla etc can be useful
as concise see-further refs. All misc stuff optional.
4. The work flow for developers already exists for accepting things
into the guix package repo, so no major new patterns for everyone to learn.
5. Anyone interested could clone the repo and pull to it for "guix-official"
bug reporting status.
WDYT?

The Guix bug database is public and can be browsed for example here
[1] or [2]. Yes, it is not friendly for upstream developer and one
needs some Guix knowledge to correctly find what one is looking for.
Debian has more friendly entry point: the package Tracker [3]. And the
webpage [4] should be improved to report our bug etc. (as Debian is
doing).

(Note that the Guix-HPC search interface is better but currently down.)




All the best,

Bug status? '.png' files with executable permissions
CAJ3okZ2ZAs+Cf0k29Aafk-LUG4FTU=wtzEJmk8pqVJ==SQ7eNQ@mail.gmail.com
Dear Bengt,

The bug report [1] points out files with unexpected permission; based
on extension filename.



It is not an security issue or the Guix packager did not carefully
check the validity of these files.

If you are security paranoid, you *have to* check by yourself all the
files using "guix build -S" because in paranoid mode you cannot trust
Guix packagers (and Guix committers neither).


In normal mode, 2 options:

a- propose a patch to change the permission for each offending package
b- report upstream

Well, at least these 3 packages docbook-xsl, faba-icon-theme, and
moka-icon-theme comes with unexpected .png file permission.


On the long term, I am not convinced that adding automatic check and
permission change based on filename extension would really add Quality
Assurance. Because we are speaking about quality, not security.


I am inclined to close this bug. What do you think?

All the best,
simon
