Descriptions
FreeRDP is a set of free and open source remote desktop protocol library and clients. In affected versions an integer overflow in `freerdp_bitmap_planar_context_reset` leads to heap-buffer overflow. This affects FreeRDP based clients. FreeRDP based server implementations and proxy are not affected. A malicious server could prepare a `RDPGFX_RESET_GRAPHICS_PDU` to allocate too small buffers, possibly triggering later out of bound read/write. Data extraction over network is not possible, the buffers are used to display an image. This issue has been addressed in version 2.11.5 and 3.2.0. Users are advised to upgrade. there are no know workarounds for this vulnerability.
FreeRDP es un conjunto de librerías y clientes de protocolos de escritorio remoto gratuitos y de código abierto. En las versiones afectadas, un desbordamiento de enteros en `freerdp_bitmap_planar_context_reset` provoca un desbordamiento de búfer de almacenamiento dinámico. Esto afecta a los clientes basados en FreeRDP. Las implementaciones de servidor y proxy basadas en FreeRDP no se ven afectadas. Un servidor malicioso podría preparar un `RDPGFX_RESET_GRAPHICS_PDU` para asignar búferes demasiado pequeños, lo que posiblemente desencadenaría posteriormente una lectura/escritura fuera de los límites. La extracción de datos a través de la red no es posible; los búferes se utilizan para mostrar una imagen. Este problema se solucionó en las versiones 2.11.5 y 3.2.0. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad.
FreeRDP is a collection of remote desktop protocol library and client software that is both free and open source. An integer overflow within freerdp_bitmap_planar_context_reset results in a heap-buffer overflow. This impacts clients built on FreeRDP. However, server implementations and proxies based on FreeRDP are unaffected. A malevolent server could create a RDPGFX_RESET_GRAPHICS_PDU to allocate buffers that are too small, potentially causing subsequent out-of-bounds reads/writes. It's important to note that data extraction over the network is not feasible; these buffers are utilized solely for displaying images.
