CVE-2026-114043

FreeRDP before 3.32.1 contains a heap-based out-of-bounds read in WinPR's clipboard PNG-to-CF DIB synthesis because winpr read png from buffer() allocates a bit-packed buffer for PNGs with bit depth below 8, while winpr bitmap write buffer() copies rows assuming one byte per pixel. A malicious RDP server can send a crafted low-bit-depth PNG clipboard payload that, when pasted by the victim, discloses megabytes of heap memory.
