Re: CVE-2021-4034: why is pkexec still a thing?

Hi Adam,

thanks for asking this question!

Due to similar horrible bugs before, I have uninstalled sudo and friends, but I never managed to uninstall pkexec due to those dependencies.

Probably because gnome-initial-setup requires it [1]?

On my system [2], apart from gnome-initial-setup, only Grsync references pkexec in its source code [3].

+1 on that pragmatic solution!

[1] https://gitlab.gnome.org/GNOME/gnome-initial-setup/-/blob/master/gnome-initial-setup/gis-pkexec.c

[2] I used `rpmreaper polkit` and walked through the source code of all the 14 direct dependencies of polkit and searched them for `pkexec`. GNOME shell mentions it a lot in source code but I cannot find it being called.
