Details

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xf_cliprdr_provide_data_ passes freed pDstData to XChangeProperty because the cliprdr channel thread calls xf_cliprdr_server_format_data_response which converts and uses the clipboard data without holding any lock, while the X11 event thread concurrently calls xf_cliprdr_clear_cached_data → HashTable_Clear which frees the same data via xf_cached_data_free, triggering a heap use after free. Version 3.23.0 fixes the issue.
