Summary
Security update for shim

Notes

Title of the patch
Security update for shim
Description of the patch
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)
