Summary
  • (es) FreeRDP es una implementación libre del Protocolo de Escritorio Remoto (RDP), publicado bajo la licencia Apache. Este problema afecta sólo a los clientes. Desbordamiento incompleto de enteros que conduce al DOS (por ejemplo, aborto debido a `WINPR_ASSERT` con los indicadores de compilación predeterminados). Cuando se proporciona un blockLen insuficiente y no se realiza la validación de longitud adecuada, se produce un desbordamiento de enteros, lo que provoca una vulnerabilidad de denegación de servicio (DOS). Este problema se ha solucionado en las versiones 2.11.0 y 3.0.0-beta3. Se recomienda a los usuarios que actualicen. No se conocen soluciones para esta vulnerabilidad.
