Security concerns and manually altered SWF files
Report of manually altered SWF files as security threat
Macromedia was informed of a potential issue with the Macromedia Flash Player, whereby a Macromedia Flash (SWF) file could be hand coded to send more information to a user's machine than the file indicates is being sent. After extensive testing and communication with the developer who initially reported this potential issue, Macromedia has found no security issue to exist. If a maliciously-coded SWF file were encountered, the effect of this "heap buffer read overflow" error would be limited to crashing a user's browser. Macromedia appreciates the support of developer community in isolating issues such as this and will continue to take any potential security issues very seriously.
