Doc Text:
A flaw was found in FreeRDP. The Android client does not validate mappedWidth and mappedHeight from RDPGFX_MAP_SURFACE_TO_WINDOW_PDU against the surface buffer. A malicious RDP server can cause android_UpdateWindowFromSurface to read beyond the allocation, leading to crashes or memory disclosure. This issue affects FreeRDP before 3.32.1 in the Android client only.

Description OSIDB Bzimport 2026-10-21 01:00:14 UTC
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.
