SUSE-SU-2024:1462-1

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 verifybuffersbat() (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 tpmrecordpcrs unless the command is in command.lst

• Removed POSTPROCESSPE_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)
