VideoLAN VLC Media Player 1.1.x - Calling Convention Remote Buffer Overflow

                                        
                                            source: https://www.securityfocus.com/bid/44909/info

VLC Media Player is prone to a remote stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data.

Attackers could exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely cause denial-of-service conditions.

Versions prior to VLC Media Player 1.1.5 for Windows are vulnerable.
