NVD description

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.
