For similar reasons, the IE rendering process ran in 32-bit mode in 64-bit systems, even if the broker process was in 64-bit mode.Īs a new browser, Edge does not have the backward compatibility concerns that hamstrung IE. To retain compatibility, the EPM sandbox was disabled by default. IE plugins would need to be re-written to support EPM, as these didn't support app containers.

Windows 8 introduced app containers, and IE 10 on Windows 8 provided a sandbox based on this technology called Enhanced Protected Mode (EPM). The PM sandbox provided a limited degree of protection. Internet Explorer 7 on Vista was the first to provide a sandbox for the browser called Protected Mode. Windows Vista first introduced mandatory integrity control to Windows. The Abandonment class can detect and deal with the following abnormalities:ĭefault EPM (Enhanced Protected Mode) Sandbox and 64-bit usage This prevent the error from spreading further, stopping any potential exploits. The Microsoft Edge HTML rendering engine found in the file edgehtml.dll introduced a new class called Abandonment.Ībandonment detects exception and throws a FAIL_FAST_EXCEPTION exception if one is detected. Memory corruption is a common class of vulnerabilities which deserves special attention. How MemGC prevents UAF exploits Abandonment This helpes prevent UAF vulnerability exploits from being successful.įigure 3. If that is the case, the heap block won’t be freed. When a heap block is freed, MemGC will first attempt to detect whether there is an existing object reference to it. MemGC is designed to mitigate these attacks. This means the attacker can access object A with attacker controlled data. Attacker fills the heap block with their own data.UAF exploits frequently follow the following steps:

These two mitigations increased the difficulty of UAF exploits, but there are still many ways to bypass these, especially in cases where the pointer to the free block didn't remain on the stack. MemoryProtection flow chart (Click to enlarge) In other situations, MemoryProtection can make UAF exploits more difficult.įigure 1. The Isolated Heap makes it harder for attackers to fill the free object. MemoryProtection can prevent UAF exploits where the free object pointer remain in the stack. To help remedy the situation, in the summer of 2014 Microsoft added two mitigation techniques to IE: one is called the Isolated Heap, which manages most DOM objects and their supporting objects.

Each Patch Tuesday cumulative update contains various fixes for UAF vulnerabilities. In the past two years, UAF vulnerabilities have been a significant problem for Internet Explorer. Edge uses MemGC to manage DOM and supporting objects's memory. MemGC uses mark-and-sweep garbage collection to help defeat use-after-free (UAF) exploits. In addition, several new features have been introduced to the browser as well.

However, much of the underlying code has been modified to remove IE-specific technologies that will not be a part of Edge. Its HTML rendering engine is a forked version of Trident (the engine found in Internet Explorer), which is now called Microsoft Edge HTML. For Windows 10, Microsoft decided to release a "new" browser (Microsoft Edge), with improved security as an important feature.Įdge is not entirely all-new. Its reputation for lack of security has become an obstacle to its development. There have been many zero-day attacks that specifically targeted vulnerabilities in Internet Explorer, such as:Īs a result, the reputation of Internet Explorer is a bit tarnished. In 2014 alone, a total of 243 memory corruption vulnerabilities in Internet Explorer were disclosed and patched.Įvery Microsoft Patch Tuesday cycle contains one bulletin that covers multiple IE vulnerabilities - the monthly "Cumulative Security Update for Internet Explorer", as it is called by Microsoft. Internet Explorer is possibly the most popular target for vulnerabilities around today.
