Microsoft yesterday re-patched Internet Explorer, the third time it's been forced to repair one of the updates from its largest-ever bug fix, which was delivered on Oct. 13.

Monday's fix targeted MS09-054, the update that patched four vulnerabilities, all "critical," in Internet Explorer (IE). According to Christopher Budd, a spokesman for the Microsoft Security Response Center (MSRC), the follow-up hotfix patches Web page display problems introduced by the update. Budd downplayed the severity of the problems, saying that the number of users affected was "limited."

A document on Microsoft's support site outlined the two issues, one that scrambles Web page elements, while the other spawns a "Type Mismatch" script error on sites that use VBScript or a mix of VBScript and JavaScript.

The new problems can crop up in any still-supported edition of IE, including IE 5.01, IE6, IE7 and the newest version, IE8, on all Windows operating systems, including Windows 7.
