    Summary: Security update for shim

    Details: This update for shim fixes the following issues: - CVE-2022-28737 was missing as reference previously. - Upgrade shim-install for bsc#1210382 After closing Leap-gap project since Leap 15.3, openSUSE Leap direct uses shim from SLE. So the ca_string is 'SUSE Linux Enterprise Secure Boot CA1', not 'openSUSE Secure Boot CA1'. It causes that the update_boot=no, so all files in /boot/efi/EFI/boot are not updated. Logic was added that is using ID field in os-release for checking Leap distro and set ca_string to 'SUSE Linux Enterprise Secure Boot CA1'. Then /boot/efi/EFI/boot/* can also be updated.
