  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. (bsc#1205588)");
