    <impact type="normal">
        <p>A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access.</p>
    </impact>
    <workaround>
        <p>There is no known workaround at this time.</p>
    </workaround>
    <resolution>
        <p>All SSSD users should upgrade to the latest version:</p>
        
        <code>
          # emerge --sync
          # emerge --ask --oneshot --verbose ">=sys-auth/sssd-2.5.2-r1"
        </code>
