Symantec has warned that Nintendo’s Wii gaming console could crash due to problems with the use of Adobe Flash files on the console.

Adobe patched the Flash flaw on 12 July, but the Opera browser used by the Wii is still vulnerable.

“The most interesting thing is that it is a cross-platform vulnerability,” said Liam OMurchu from Symantec’s Security Response team.

“Due to the fact that Flash can run in different browsers and on different platforms, the discovery of this one vulnerability could leave all Flash-enabled operating systems and devices open to the attack, including some advanced smartphones.

“The vulnerability has already been tested on Windows, Apple Mac, and some Linux distributions, but many other devices that are Flash-enabled could be affected by the problem too.”

The malware to exploit the flaw in a Windows environment has been posted on a popular exploit website and uses specially crafted .FLV Flash files.

These can be uploaded to popular video sharing sites and the Symantec team has warned such sites to begin scanning for corrupted files.
