CVE-2026-31897

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, there is an out-of-bounds read in freerdpbitmapdecompressplanar when SrcSize is 0. The function dereferences srcp which points to pSrcData without first verifying that SrcSize = 1. When SrcSize is 0 and pSrcData is...

CVE-2026-31806

Summary: CVE-2026-31806 affects FreeRDP prior to 3.24.0, where the gdi_surface_bits() handler (NSCodec path) can process SURFACE_BITS_COMMAND messages with unsafe bmp.width/bmp.height values, enabling a heap buffer overflow by crafting server data. The issue arises when width/height are not prope...

CVE-2026-31806 FreeRDP has a Heap Buffer Overflow in nsc_process_message() via Unchecked SURFACE_BITS_COMMAND Bitmap Dimensions

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, the gdisurfacebits function processes SURFACEBITSCOMMAND messages sent by the RDP server. When the command is handled using NSCodec, the bmp.width and bmp.height values provided by the server are not properly...
