When an OLE paste consumer (e.g. explorer.exe) calls IStream::Read with a fixed-size buffer of cb bytes, CliprdrStream_Read requests file contents from the RDP server and then copies the response into the caller&#39;s buffer using the server-supplied length (req_fsize) instead of cb. A malicious or compromised RDP server can return an oversized CB_FILECONTENTS_RESPONSE, causing an out-of-bounds write of attacker-controlled data into the paste consumer&#39;s heap buffer when a user pastes server-offered clipboard file contents.</p> <p><strong>Affected:</strong> FreeRDP</p> <p>FreeRDP before 3.30.0 (&lt;= 3.29.0) contains a heap-based buffer overflow in the Windows clipboard client&#39;s CliprdrStream_Read function (client/Windows/wf_cliprdr.c).
