Published:October 21, 2026
Updated:October 21, 2026
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 RDPGFX_MAP_SURFACE_TO_WINDOW_PDU with oversized dimensions, causing android_UpdateWindowFromSurface to copy heap memory beyond the allocation, leading to crashes or memory disclosure.
