Leading security firm Symantec has confirmed that a vulnerability in Adobe Flash can work on the Wii via the systems opera browser. The exploit can cause the Wii to freeze and runs through a normal Youtube type .FLV format. According to Symantec its not a big threat with there being no public exploits for Linux or Mac systems, so while the code can freeze up a Wii it is unlikely that anything in terms of homebrew will come of it.
