Dangerzone was failing to convert documents in Qubes due to missing
client-side dependencies. In particular poppler-utils, ghostscript and
graphicsmagick.
Fixes#647
Our security scans previously alerted us on critical CVEs that have a
fix. In this commit, we ask to be alerted on CVEs that don't have a fix
yet, so that we can have them in our radar.
Since the introduction of these security checks, we have only once
encountered a case where our container was vulnerable to a CVE that
Alpine Linux had not fixed yet. This means that the maintenance burden
of this change will probably be minimal.
In Qubes the disposable netVM is internet connected. For this reason,
on Qubes we chose create our own disposable VM (dz-dvm). However, in
reality this could still be bypassed since dz-dvm had the default
disposable dispvm.
By setting the default_dispvm to '' we prevent this bypass. For VMs
users who have already followed the setup instructions, the following
command should (to be ran in dom0) will fix this issue:
qvm-prefs dz-dvm default_dispvm ''
By using `--skip / --extend-skip .gitignore`, we actually never read the
.gitignore file. We have to use `--skip-gitignore` instead.
This requires Git in the development environment, so we need to install
Git in our CI runners as well.
Fix a bug in the "Change Selection" action, whereby changing your
selection and picking files from another directory results in:
"Dangerzone does not support adding documents from multiple
locations. The newly added documents were ignored."
To fix this, change the output directory when we change selection as
well.
The original intention of leaving the update checkbox in the hamburger
menu was to let non-supported Linux distros (e.g. compiled from source)
to check for updates. However, on Linux it ended up being disabled
forcefully by default on startup.
This takes into account an overriden update checkbox.
Fixes#596
This commit fixes 3 small issues with the way we produce our Qubes RPM:
1. The `.exists()` method follows symlinks by default, whereas we want
to check if a symlink exists. This functionality has been added in
Python
3.12.
Instead of checking if a symlink exists and then removing it, simply
remove it and don't throw an error if it doesn't exist in the first
place.
2. The `dz.Convert*` policies were not installed with the executable bit
set, therefore the qube could not start.
3. The `dz.ConvertDev` policy in particular had an ambiguous shebang,
thus we change it to explicitly call Python3
If a Qubes conversion encounters an exception that is not a subclass of
ConversionException, it will still show a preview of a file that does
not exist.
Send an error progress report in that case, so that the GUI code can
detect that an error occurred and not open a file preview
Fixes#581
Create a temporary dir before the conversion begins, and store every
file necessary for the conversion there. We are mostly concerned about
the second stage of the conversion, which runs in the host. The first
stage runs in a disposable qube and cleanup is implicit.
Fixes#575Fixes#436
Extend the PixelsToPDF converter by adding an additional `tempdir`
argument. This argument can be used to make the conversion use a
different temporary directory other than `/tmp`.
For containers, this extra arguments makes no difference, as it won't be
used. For Qubes, this argument will allow storing files in a temporary
dir that will be cleaned up once the conversion completes. Previously,
these files would linger in the user's `/tmp`.
Refs #575
If a command encounters an error or times out during the second stage of
the conversion in Qubes, handle it the same way as we would have handled
it in the first stage:
1. Get its error message.
2. Throw an UnexpectedConversionError exception, with the original
message.
Note that, because the second stage takes place locally, users will see
the original content of the error.
Refs #567Closes#430
This should only affect the alpha version of Qubes OS (in containers
it only allows the attacker to control the timeout). In short, an
attacker could have PDF metadata that would show before "Pages:" in
the `pdfinfo` command output and this would essentially override the
number of pages measured in the server. This could enable the attacker
to shorten the number of pages of a document for example.
Fixes#565
When qrexec-client-vm fails, it could be a symptom of various issues:
- the system being out of RAM
- dz-dvm not existing
The exit code is the same in all cases (126), which makes it
particularly tricky to solve in the client application. For this reason
the approach is now to tell the user to see the qubes error notification
on the top right of their screen.
Add a sanity check at the end of the conversion from doc to pixels, to
ensure that the resulting document will have the same number of pages as
the original one.
Refs #560
Stream page data back to the caller, immediately after we read them from
pdftoppm. This way, we have more accurate progress reports and timeouts.
