Package: thunderbird
Version: 1:52.4.0-1
I turned on AppArmor and Thunderbird stopped opening links for me. dmesg
has the following denial message:
[ 3795.153239] audit: type=1400 audit(1509283418.100:64):
apparmor="DENIED" operation="exec" profile="thunderbird"
name="/opt/google/chrome-beta/google-chrome-beta" pid=31896
comm="thunderbird" requested_mask="x" denied_mask="x" fsuid=1000 ouid=0
I think there needs to be some kind of defined way for browsers to be
allowed to be executed. I understand that I use a browser that is not in
the distribution, which makes this even more important. In this case the
browser is literally set as the xdg default:
$ xdg-settings get default-web-browser
google-chrome-beta.desktop
/etc/apparmor.d/abstractions/ubuntu-browsers includes the regular
google-chrome:
/opt/google/chrome/google-chrome Cx -> sanitized_helper,
Literally the only browser Thunderbird should be able to execute is the
one configured as the default, not some set of ancient and potentially
exploitable other browsers (like some compiled against old webkit
versions), looking at the current list in the abstraction.
I suppose one way would be to always launch some kind of
sensible-browser binary and let that call out to the default browser
only. Which might be what sanitized_helper is already trying to
accomplish. Except that the abstraction leaks into the... abstraction. :)
Another way would be to let browser packages ship a file that allows
their execution and then the installed ones are automatically available
to Thunderbird (or another browser-spawning program). In this case
Chrome would need to start shipping such a file.
Kind regards and thanks
