Buffer overflow in the xrdp_bitmap_invalidate function in xrdp/xrdp_bitmap.c in xrdp 0.4.1 and earlier allows remote attackers to execute arbitrary code via a crafted request.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
