Microsoft is to release five security patches for its products this week, including a highly anticipated Internet Explorer fix to sort out a bug hackers have been exploiting over the past two weeks.
The company also plans to repair three other flaws in Windows and an unspecified problem in Office that is rated as a "moderate" risk.
Because of the severity of the IE bug, known as the create TextRange () vulnerability, two security suppliers, eEye Digital Security and Determina, have already offered free fixes for it.
Some of Microsoft’s new patches will also include ActiveX changes to bring the company in line with a 2003 court decision relating to patents held by Eolas Technologies and the University of California. These changes will alter the way IE works with multimedia technologies like Flash and QuickTime, forcing web developers to make changes to their sites.
It’s not been a good few weeks for Microsoft, with Vista delayed until next year, and concerns over the delay in sorting out the latest vulnerability.
