Descriptions

The SAP Internet Graphics Server (IGS), 7.20, 7.20EXT, 7.45, 7.49, 7.53, has insufficient request validation (for example, where the request is validated for authenticity and validity) and under certain conditions, will process invalid requests. Several areas of the SAP Internet Graphics Server (IGS) did not require sufficient input validation. Namely, the SAP Internet Graphics Server (IGS) HTTP and RFC listener, SAP Internet Graphics Server (IGS) portwatcher when registering a portwatcher to the multiplexer and the SAP Internet Graphics Server (IGS) multiplexer had insufficient input validation and thus allowing a malformed data packet to cause a crash.

SAP Internet Graphics Server (IGS), 7.20, 7.20EXT, 7.45, 7.49 y 7.53 tiene una validación insuficiente de las peticiones (por ejemplo, donde la petición se valida para la autenticidad y validez) y, en ciertas condiciones, procesará las peticiones inválidas. Varias áreas de SAP Internet Graphics Server (IGS) no requirieron una validación de entradas suficiente. Concretamente, el escuchador HTTP y RFC de SAP Internet Graphics Server (IGS) y SAP Internet Graphics Server (IGS) portwatcher, al registrar un portwatcher al multiplexer y el multiplexer de SAP Internet Graphics Server (IGS) tenía una validación de entradas insuficiente, permitía que un paquete de datos mal formados provocase un cierre inesperado.
