Affected Products:
* SUSE Linux Enterprise High Performance Computing 15 SP2
* SUSE Linux Enterprise High Performance Computing 15 SP2 LTSS 15-SP2
* SUSE Linux Enterprise Server 15 SP2
* SUSE Linux Enterprise Server 15 SP2 LTSS 15-SP2
* SUSE Linux Enterprise Server for SAP Applications 15 SP2
An update that solves seven vulnerabilities, contains one feature and has five
security fixes can now be installed.
## Description:
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)
