Subject: Yahoo messenger file extension spoof vulnerability

Hi, i discover a possible file name extension spoofing in yahoo messenger 8.0.0.863 (lastest),obviously this requires that the option "Hide extension for known file types" is enabled in Windows, you need to send a file with this name for example: Annakournikova and her friends.jpg.exe or Trojan.txt.exe Info.txt.exe The  characters hide the extension.
