FreeRDP before 3.32.1 contains a heap out-of-bounds read vulnerability in the Android client that allows malicious RDP servers to read beyond surface buffers by supplying unvalidated mappedWidth and mappedHeight values. Attackers can send a crafted RDPGFXMAPSURFACETOWINDOWPDU with oversized dimensions, causing androidUpdateWindowFromSurface to copy heap memory beyond the allocation, leading to crashes or memory disclosure.
