And I've run `grub-install` with my EFI dir mounted. What's interesting is the version in EFI is different than the version staged by the package:

```
# sum /usr/lib/shim/shimx64.efi /boot/EFI/EFI/debian/shimx64.efi
47979   918 /usr/lib/shim/shimx64.efi
36147   913 /boot/EFI/EFI/debian/shimx64.efi
```

You must compare with /usr/lib/shim/shimx64.efi.signed from shim-signed.

Ah, thanks. At least I know I did the grub-install right:

```
$ sum /usr/lib/shim/shimx64.efi.signed /boot/EFI/EFI/debian/shimx64.efi
36147   913 /usr/lib/shim/shimx64.efi.signed
36147   913 /boot/EFI/EFI/debian/shimx64.efi
```

So I guess that means that the shimx64.efi that's distributed with shim-signed is, in fact, vulnerable, as proposed in the original bug.

Any timeline on updating it?
