  script_tag(name:"insight", value:"This update for shim fixes the following issues:

  * Update shim-install to set the TPM2 SRK algorithm (bsc#1213945)

  * Limit the requirement of fde-tpm-helper-macros to the distro with
      suse_version 1600 and above (bsc#1219460)

  Update to version 15.8:

  Security issues fixed:

  * mok: fix LogError() invocation (bsc#1215099,CVE-2023-40546)

  * avoid incorrectly trusting HTTP headers (bsc#1215098,CVE-2023-40547)

  * Fix integer overflow on SBAT section size on 32-bit system
      (bsc#1215100,CVE-2023-40548)

  * Authenticode: verify that the signature header is in bounds
      (bsc#1215101,CVE-2023-40549)

  * pe: Fix an out-of-bound read in verify_buffer_sbat()
      (bsc#1215102,CVE-2023-40550)

  * pe-relocate: Fix bounds check for MZ binaries (bsc#1215103,CVE-2023-40551)

  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

  * Adopt TPM 2.0 Key File for grub2 TPM 2.0 protector

  * Use the long name to specify the grub2 key protector

  * cryptodisk: support TPM authorized policies

  * Do not use tpm_record_pcrs unless the command is in command.lst

  * 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.
