{"schemaVersion":3,"id":"SUSE-SU-2024:1461-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Security update for shim\n\nThis update for shim fixes the following issues:\n\n- Update shim-install to set the TPM2 SRK algorithm (bsc#1213945)\n- Limit the requirement of fde-tpm-helper-macros to the distro with\n  suse_version 1600 and above (bsc#1219460)\n\nUpdate to version 15.8:\n\nSecurity issues fixed:\n\n- mok: fix LogError() invocation (bsc#1215099,CVE-2023-40546)\n- avoid incorrectly trusting HTTP headers (bsc#1215098,CVE-2023-40547)\n- Fix integer overflow on SBAT section size on 32-bit system (bsc#1215100,CVE-2023-40548)\n- Authenticode: verify that the signature header is in bounds (bsc#1215101,CVE-2023-40549)\n- pe: Fix an out-of-bound read in verify_buffer_sbat() (bsc#1215102,CVE-2023-40550)\n- pe-relocate: Fix bounds check for MZ binaries (bsc#1215103,CVE-2023-40551)\n\n\nThe 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.\n\n- Generate dbx during build so we don't include binary files in sources\n- Don't require grub so shim can still be used with systemd-boot\n- Update shim-install to fix boot failure of ext4 root file system\n  on RAID10 (bsc#1205855)\n- Adopt the macros from fde-tpm-helper-macros to update the\n  signature in the sealed key after a bootloader upgrade\n\n- Update shim-install to amend full disk encryption support\n  - Adopt TPM 2.0 Key File for grub2 TPM 2.0 protector\n  - Use the long name to specify the grub2 key protector\n  - cryptodisk: support TPM authorized policies\n  - Do not use tpm_record_pcrs unless the command is in command.lst\n\n- Removed POST_PROCESS_PE_FLAGS=-N from the build command in shim.spec to\n  enable the NX compatibility flag when using post-process-pe after\n  discussed with grub2 experts in mail. It's useful for further development\n  and testing.
