IE 8 gets new breach — and a new patch

No comments April 1st, 2010

The most-worrisome security flaw revealed by the Pwn2Own contest was the Internet Explorer 8 hack. Dutch researcher Peter Vreugdenhil won $10,000 by circumventing Windows 7’s two best anti-malware controls, Address Space Load Randomization (ASLR) and Data Execution Prevention (DEP).

An independent security expert, Vreugdenhil immediately published a paper, available on his Web site, describing in general terms how he did it. (He states he will not publicly reveal the exact exploits used.) He was able to take over a fully up-to-date Windows 7 system in two steps. First, he managed to evade ASLR and get the memory address of a Windows 7 .dll file. Next, he disabled DEP by using a previously known exploit.

Circumventing DEP is especially troubling: Microsoft relies heavily on DEP to keep out new malware that’s unknown to antivirus applications — so-called zero-day attacks.

A March 30 Microsoft Security Response Center bulletin announced the unscheduled release of an Internet Explorer update. According to the bulletin, this release was not related to the IE 8 vulnerability revealed at CanSecWest (which Microsoft is still investigating) but is a cumulative security patch for all versions of Internet Explorer.

Security Bulletin MS10-018 (980182) is marked critical, addresses 10 Internet Explorer security flaws, and should be installed as soon as possible. For more on this and a large Apple patch release, see contributing editor Susan Bradley’s Patch Watch column in today’s paid content.

Security fixes, JavaScript update bog down Internet Explorer 8

No comments November 5th, 2009

I was surprised to see an article by Scott in beta news website, where he mentions that the Security fixes, and JavaScript update will bog down IE8. He mentions in the article that they have noticed a trend of IE8 performance dragging down over time, while every other major Windows browser in the field was headed the other direction — and fast. Early this month, when Firefox 3.6 Beta 1 appeared imminent (and still is at this moment), we calculated the performance difference between IE8 and IE7 at about 75%.

However, after installing the security fixes that was released in the month of October, and the update for Microsoft’s JavaScript (JScript) engine, the performance has averaged down to 54%.

I hope Microsoft will further look in at these issues and present a browser which will compete with other browsers.
