It seems that the third-party patch released by Zeroday Emergency Response Team, or ZERT, has lit a fire up Microsoft's proverbial behind. The software giant has released a "critical" security fix for Windows two weeks before its scheduled release date.
It fixes a flaw in in the way Internet Explorer 6 handles certain graphics, which may allow malicious software to be loadedwhen the user clicks on a malicious link on a Web site or an email message.
The patch can be installed using Windows Update service or downloaded in the security bulletin MS06-055 article.
