Based on the recent success of an infectious program dubbed SWF/LFM-926, antivirus
companies warned that future Macromedia Flash animations may harbor computer
viruses. SWF/LFM-926 infects the Flash files on a PC whenever an affected movie
is played.
While SWF/LFM-926 is not currently considered very serious, future exploits of the Flash vulnerability could be more malicious. As we go to press, Macromedia is releasing a fix to disable the file association between Flash files and the local Flash player. The company also plans to eliminate the vulnerability altogether in the next version of Flash.
