This issue is fixed in continuous build 1.26.0.299."

Antes de la compilación continua 1.26.0.299, un servidor Deskflow remoto no autenticado puede enviar valores kMsgDSetOptions (DSOP) a ServerProxy::setOptions() en src/lib/client/ServerProxy.cpp de modo que el valor que sigue a una opción modificadora envenena m_modifierTranslationTable, después de lo cual ServerProxy::translateKey() o ServerProxy::translateModifierMask() indexa los arrays s_translationTable o s_masks de siete filas fuera de los límites, divulgando cuatro bytes en un desplazamiento relativo seleccionado por el atacante o bloqueando el cliente conectado; un recuento de opciones impar también causa una lectura de OptionsList fuera de los límites. Este problema está solucionado en la compilación continua 1.26.0.299."
