In Real Player 20.0.8.310, there is a DCP:// URI Remote Arbitrary Code Execution Vulnerability. This is an internal URL Protocol used by Real Player to reference a file that contains an URL. It is possible to inject script code to arbitrary domains. It is also possible to reference arbitrary local files.

In Real Player 20.0.7.309 and 20.0.8.310, external::Import() allows download of arbitrary file types and Directory Traversal, leading to Remote Code Execution. This occurs because it is possible to plant executables in the startup folder (DLL planting could also occur).

In Real Player 20.0.8.310, the G2 Control allows injection of unsafe javascript: URIs in local HTTP error pages (displayed by Internet Explorer core). This leads to arbitrary code execution.
