Description OSIDB Bzimport 2026-11-03 15:14:13 UTC 
FreeRDP before 3.32.2 contains a denial of service vulnerability in WinPR's winpr_read_png_from_buffer() and winpr_convert_from_jpeg(), which lack libpng/libjpeg error handling. A malicious RDP server or MITM can offer a malformed PNG or truncated JPEG clipboard payload, causing the client to abort or exit.
