Microsoft’s Internet Explorer browser has been hit by the third reported security bug this week.
As previously reported, Microsoft is already considering fixes for two other bugs reported to the company this week, which both potentially allow remote attackers to take over users’ systems.
Now, UK-based internet security researcher Computer Terrorism has reported another “critical” IE bug that could allow attackers to take over users’ machines.
The latest reported problem relates to the way IE processes information using the createTextRange method.
If the browser is pointed at specially crafted malicious code, attackers could potentially corrupt the PC’s memory and trick it into running unauthorised software.
Computer Terrorism says it has tested the flaw on the current IE 6 and the new IE 7 beta 2 release and both were vulnerable.
Microsoft is now believed to be considering issuing a patch for the latest flaw. The company’s next scheduled patching date is Tuesday 11 April.
