CVE-2023-39355

Estado: ModificadaCrítica (9.8)—

FreeRDP es una implementación gratuita del Protocolo de Escritorio Remoto (RDP), publicado bajo la licencia Apache. Las versiones de FreeRDP en la rama de lanzamiento 3.x anteriores a beta3 están sujetas a un uso después de liberación al procesar paquetes 'RDPGFX_CMDID_RESETGRAPHICS'. Si 'context->maxPlaneSize' es 0, 'context->planesBuffer' será liberado. Sin embargo, sin actualizar 'context->planesBuffer', esto conduce a un vector de exploit de uso después de liberación. En la mayoría de los entornos, esto solo debería resultar en un fallo. Este problema ha sido abordado en la versión 3.0.0-beta3 y se aconseja a los usuarios de las versiones beta 3.x que actualicen. No se conocen soluciones alternativas para esta vulnerabilidad.
