    <description>
        <p>Multiple vulnerabilities have been discovered in rsyslog. Please review the CVE identifiers referenced below for details.</p>
    </description>
    <impact type="normal">
        <p>Modules for TCP syslog reception have a heap buffer overflow when octet-counted framing is used. The attacker can corrupt heap values, leading to data integrity issues and availability impact. Remote code execution is unlikely to happen but not impossible.</p>
    </impact>
    <workaround>
        <p>There is no known workaround at this time.</p>
    </workaround>
    <resolution>
        <p>All rsyslog users should upgrade to the latest version:</p>
        
        <code>
          # emerge --sync
          # emerge --ask --oneshot --verbose ">=app-admin/rsyslog-8.2206.0"
        </code>
