Freerdp · Freerdp · CVE-2026-110839
FreeRDP 3.3.0 before 3.32.0, when built with WINPR UTILS IMAGE JPEG=ON, has a heap-based out-of-bounds write in winpr convert from jpeg because grayscale JPEG buffers are sized from one input component rather than three BGR output components. A malicious RDP server can offer a grayscale JPEG via clipboard redirection, corrupting client memory and crashing it when the item is pasted as CF DIB bitmap data.
