<p>An update that solves seven vulnerabilities, contains one feature and has five security fixes can now be installed.</p>
<h2>Description:</h2>
<p>This update for shim fixes the following issues:</p>
<ul>
<li>Update shim-install to set the TPM2 SRK algorithm (bsc#1213945)</li>
<li>Limit the requirement of fde-tpm-helper-macros to the distro with
suse_version 1600 and above (bsc#1219460)</li>
</ul>
<p>Update to version 15.8:</p>
<p>Security issues fixed:</p>
<ul>
<li>mok: fix LogError() invocation (bsc#1215099,CVE-2023-40546)</li>
<li>avoid incorrectly trusting HTTP headers (bsc#1215098,CVE-2023-40547)</li>
<li>Fix integer overflow on SBAT section size on 32-bit system (bsc#1215100,CVE-2023-40548)</li>
<li>Authenticode: verify that the signature header is in bounds (bsc#1215101,CVE-2023-40549)</li>
<li>pe: Fix an out-of-bound read in verify_buffer_sbat() (bsc#1215102,CVE-2023-40550)</li>
<li>pe-relocate: Fix bounds check for MZ binaries (bsc#1215103,CVE-2023-40551)</li>
</ul>
<p>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.</p>
<ul>
<li>Generate dbx during build so we don't include binary files in sources</li>
<li>Don't require grub so shim can still be used with systemd-boot</li>
<li>Update shim-install to fix boot failure of ext4 root file system
on RAID10 (bsc#1205855)</li>
<li>
<p>Adopt the macros from fde-tpm-helper-macros to update the
signature in the sealed key after a bootloader upgrade</p>
</li>
<li>
<p>Update shim-install to amend full disk encryption support</p>
</li>
<li>Adopt TPM 2.0 Key File for grub2 TPM 2.0 protector</li>
<li>Use the long name to specify the grub2 key protector</li>
<li>cryptodisk: support TPM authorized policies</li>
<li>
<p>Do not use tpm_record_pcrs unless the command is in command.lst</p>
</li>
<li>
<p>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)</p>
</li>
</ul>
