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)

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
