As some might have seen, flash was recently hit by a nasty little security exploit, which allowed the execution of malicious code. Version 6.0.29 is out @ macromedia.com. Thanks to Henrik whos site i suppose i should plug - its worth a look here!
"Description:
A vulnerability in the parameter handling to the Flash OCX, which could lead to the execution of attacker supplied code via email, web or any other avenue in which Internet Explorer is used to display html that an attacker can supply. This includes software which uses the web browser activex.
All users of Internet Explorer are potentially affected because this is a Macromedia signed ocx. We advise them to upgrade their flash version immediately to version 6, revision 29."
