Heap exploitation is getting harder. The heap protection features in the latest versions of Windows have been effective at stopping the basic exploitation techniques. In most cases bypassing the protection requires a great degree of control over the allocation patterns of the vulnerable application.
This presentation introduces a new technique for precise manipulation of the browser heap layout using specific sequences of JavaScript allocations. This allows an attacker to set up the heap in any desired state and exploit difficult heap corruption vulnerabilities with great reliability and precision.
This talk will begin with an overview of the current state of browser heap exploitation and the unreliability of many heap exploits. It will continue with a discussion of Internet Explorer heap internals and the techniques for JavaScript heap manipulation. I will present a JavaScript heap exploitation library that exposes an abstract heap manipulation API. Its use will be demonstrated by exploit code for two complex heap corruption vulnerabilities.
The talk will focus on Internet Explorer exploitation, but the general technique presented is applicable to other browsers as well.
