Summary

Additionally, this update blocks old, insecure versions of GRUB. Thus an
update to a signed GRUB 2.06-3~deb10u3 package as released in DLA 3190-2
must be in place prior to updating the shim packages.

For Debian 10 buster, this problem has been fixed in version
15.7-1~deb10u1.

We recommend that you upgrade your shim packages.

For the detailed security status of shim please refer to
its security tracker page at:
