<p>An update that solves one vulnerability can now be installed.</p>
<h2>Description:</h2>
<p>This update for shim fixes the following issues:</p>
<ul>
<li>
<p>CVE-2022-28737 was missing as reference previously.</p>
</li>
<li>
<p>Upgrade shim-install for bsc#1210382</p>
</li>
</ul>
<p>After closing Leap-gap project since Leap 15.3, openSUSE Leap direct
uses shim from SLE. So the ca_string is 'SUSE Linux Enterprise Secure Boot
CA1', not 'openSUSE Secure Boot CA1'. It causes that the update_boot=no,
so all files in /boot/efi/EFI/boot are not updated.</p>
<p>Logic was added that is using ID field in os-release for
checking Leap distro and set ca_string to 'SUSE Linux Enterprise Secure
Boot CA1'. Then /boot/efi/EFI/boot/* can also be updated.</p>
<h2>Patch Instructions:</h2>
<p>
To install this SUSE Important update use the SUSE recommended
installation methods like YaST online_update or "zypper patch".<br/>
