NOTE: Some third parties have indicated the fix in 3.5 does not adequately address the vulnerability. The argument is that the proposed patch prevents dmidecode from writing to an existing file. However, there are multiple attack vectors that would not require overwriting an existing file that would provide the same level of unauthorized privilege escalation (e.g. creating a new file in /etc/cron.hourly)."

NOTA: Terceros han indicado que la correcci\u00f3n implementada en la versi\u00f3n 3.5 no aborda adecuadamente la vulnerabilidad.
