Critical Microsoft Security Flaw

Microsoft disclosed today that most active versions of Windows (2000 through Vista) have a serious security flaw in how they handle animated mouse cursors. In this security advisory, Microsoft describes that, clicking on a link in an email message, stumbling across a malicious website, or even a legitimate website that’s been compromised can lead to unintended code execution. Just about the only safe environment is Windows Vista with IE7 in full lock down mode. This security threat is considered a zero-day exploit, meaning that examples of exploitation have already been observed in the wild, and currently there is no fix from Microsoft. So, keep running your windows update over the next few days or check back here for links to helpful resources. In the meantime, don’t open emails from people you don’t know, and stick to surfing the websites that you do know… you know… normal, safe Internet practices.

Security Firm eEye Research has released an unofficial security patch in response to the animated cursor vulnerability. Please see their press release for details. However, Microsoft is expected to release their official hotfix or patch tomorrow.
[UPDATE 2007-04-03 3:00 PM PST]
Indeed, Microsoft has released a security patch out of cycle in order to guard against known, real-worl threats from the Animated Cursor flaw. If you have not done so already, please run Windows Update to grab the most recent patches.
