This update for shim fixes the following issues:
Update to version 15.8:
Security issues fixed:
The NX flag is disable which is same as the default value of shim-15.8, hence, not need to enable it by this patch now.
Generate dbx during build so we don't include binary files in sources
Don't require grub so shim can still be used with systemd-boot
Update shim-install to fix boot failure of ext4 root file system on RAID10 (bsc#1205855)
Adopt the macros from fde-tpm-helper-macros to update the signature in the sealed key after a bootloader upgrade
Update shim-install to amend full disk encryption support
Removed POST_PROCESS_PE_FLAGS=-N from the build command in shim.spec to enable the NX compatibility flag when using post-process-pe after discussed with grub2 experts in mail. It's useful for further development and testing. (bsc#1205588)
