Microsoft has issued confirmation that its "critical" Internet Explorer patches had to be pulled after a hiccup caused some of the downloads to be corrupted. Seemingly, the IE patch from the Microsoft Download centre was where the problem lay. The cumulative IE update was part of the August release of six security bulletins from Microsoft to address eight vulnerabilities in the Windows operating system. Patches posted on Microsoft Update and Windows Update were not affected by the glitch.

"Shortly after we released the updates this morning we found that several of the Internet Explorer updates provided only to the Download Center were corrupted, breaking the digital signature and preventing them from installing," a post on the official Internet Explorer Weblog said.
