A fix for a widely exploited flaw in Internet Explorer is among five security patches Microsoft told users to expect this week.

Following weeks of speculation whether the CreateTextRange vulnerability would force the software giant to break from tradition and release a special patch, Microsoft said last week the patch is among four others slated for April 11.

The company expects to release five security patches: four (including one deemed "critical") affect the Windows operating system and one addresses a "moderate" vulnerability in Microsoft Office.

"One of the updates will be a cumulative Internet Explorer update that addresses the publicly known 'CreateTextRange' vulnerability," Microsoft wrote in an advance notification.

The official patch follows a series of third-party fixes unveiled by security firms as a temporary solution.
