Summary
FreeRDP 3.10.0 through 3.32.2 Heap Buffer Overflow in WinPR PNG Conversion
Details

FreeRDP 3.10.0 through 3.32.2 contains a heap buffer overflow in the WinPR png_write_data callback that writes past the buffer after a realloc failure. A malicious RDP clipboard peer can supply a large CF_DIB image that triggers out-of-bounds memcpy during PNG conversion, causing a client crash.
