Microsoft Releases Out-of-Band Patch For IE Vulnerability

Released as a MSI package, the patch is described as a workaround that leverages the Windows application compatibility toolkit to make a small change to MSHTML.DLL in memory every time the DLL is loaded by Internet Explorer. Microsoft previously recommended IE users to take this step manually, while the patch automates the task. Microsoft provides an installation guide for the workaround as well as information to uninstall the patch again.

Microsoft stressed that the workaround is only effective if all recent security updates for IE have been installed as well.

The company confirmed existing attacks that exploit the vulnerability. However, Microsoft said that "only 32-bit versions of Internet Explorer" are targeted and attacks "rely on third-party browser plugins to either perform efficient heap-spray in memory and/or to bypass the built-in mitigations of Windows Vista and 7 such as DEP and ASLR." However, users can further reduce the risk of a successful attack by updating their Java version from Java 6 to 7.

    And yet another reason why you should move away from IE and use Chrome/Firefox

    IE should be renamed to Swiss Cheese. It has that many holes.

    Too bad people still use old IE's, too bad Microsoft did such a bad browser; but that's nice of Microsoft, launching a critical update to defunct software, unlike most companies that just don't care.
