If a user connects to a malicious or compromised VNC server, specially-crafted data could result in memory corruption, possibly allowing arbitrary code to be executed with the privileges of the running guacd process.\n\nUsers are recommended to upgrade to version 1.5.4, which fixes this issue."

Si un usuario se conecta a un servidor VNC malicioso o comprometido, los datos especialmente manipulados podr\u00edan da\u00f1ar la memoria, permitiendo posiblemente que se ejecute c\u00f3digo arbitrario con los privilegios del proceso guacd en ejecuci\u00f3n.
