CVE-2023-39353

Estado: ModificadaCrítica (9.1)—

FreeRDP es una implementación gratuita del Protocolo de escritorio remoto (RDP) , publicada bajo la licencia Apache. Las versiones afectadas están sujetas a una validación de compensación faltante que conduce a una lectura fuera de límites. En el archivo `libfreerdp/codec/rfx.c` no hay validación de compensación en `tile->quantIdxY`, `tile->quantIdxCb` y `tile->quantIdxCr`. Como resultado, una entrada manipulada puede dar lugar a un acceso de lectura fuera de límites, lo que a su vez provocará un bloqueo. Este problema se solucionó 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.
