    <description>
        <p>LibreOffice links using the vnd.libreoffice.command scheme could be constructed to call internal macros with arbitrary arguments. Which when clicked on, or activated by document events, could result in arbitrary script execution without warning.</p>
    </description>
    <impact type="high">
        <p>An attacker able to coerce a victim into opening a crafted LibreOffice document and execute certain actions with it could achieve remote code execution.</p>
    </impact>
    <workaround>
        <p>There is no known workaround at this time.</p>
    </workaround>
    <resolution>
        <p>All LibreOffice users should upgrade to the latest version:</p>
        
        <code>
          # emerge --sync
          # emerge --ask --oneshot --verbose ">=app-office/libreoffice-7.3.6.2"
        </code>
        
        <p>All LibreOffice binary users should upgrade to the latest version:</p>
        
        <code>
          # emerge --sync
          # emerge --ask --oneshot --verbose ">=app-office/libreoffice-bin-7.3.6.2"
