Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the clipboard process. An attacker can achieve arbitrary code execution by sending a specially crafted CLIPRDR_FILE_CONTENTS_RESPONSE PDU with an oversized data payload from a malicious RDP server, leading to heap memory corruption when a user performs a paste operation.
