According to TechWorld, a "highly critical hole" found in the popular media player, WinAMP, can open a window to hackers that only by running Fasttracker 2 ".xm" media files through a malicious website... We recommend upgrading to the latest version of the player inmediately.
It is possible to cause a heap overflow and so run code on the person's system. A ".xm" file is not needed however, as the software runs through all supported files with the same faulty piece of code. This greatly increases the opportunities hackers may have to con someone into clicking a link and so providing them with system access.
