FreeRDP from 3.14.1 before 3.32.0 contains an integer underflow in the WinPR BMP writer, where a mismatched stride calculation passes SIZE MAX - 3 to Stream Zero for sub-byte images. A malicious RDP clipboard peer can return a crafted 1-bpp BMP processed by clipboard synthesize image format to bmp for CF DIB/CF DIBV5, crashing the client or causing an out-of-bounds write.
