Ah finally a decent 0-day exploit tracker, one that isn’t underground and could be fairly useful to everyone.

0-day as basically stated in the article is an exploit not known publicly or available publicly well before any patches are available, some private groups often have exploits for a year or more before someone else discovers them, makes them public and they inevitably get fixed.

Like the famous remote exploit in Windows RPC, private groups had that for almost 2 years before it became public.

Scary eh?

Security firm eEye has created what’s described as the industry’s first site designed solely to track zero-day vulnerabilities, flaws where exploits are available prior to the release of security patches.

eEye’s zero-day tracking site provides detailed information on flaws and remediation strategies to users. The site will be maintained by security researchers at eEye Research, who have a track record of unearthing new security bugs, and is essentially an eEye gig rather than a cross-industry effort.

It’s a good idea even if it’s not an industry effort it’s solely an eEye effort, I’m glad someone has done it and eEye has a strong capable team, so it should be fairly relevant if it’s kept up to date.

However, eEye invites other interested parties to contribute suggestions on flaws that merit inclusion on its list. eEye said it created the site, which includes information on how long flaws have remained unfixed, in response to the growing number of zero-day exploits.

In other security tracking news, security notification firm Secunia has released a tool designed to determine insecure versions of popular software packages (such as browsers, IM clients, and media players) on consumer’s PC.

Secunia’s Software Inspector provides users with advice on what to do if they are running insecure software packages.

Both eEye zero-day tracking site and Secunia’s Software Inspector are available free of charge.

Duster is the Dead/Uninitialized Stack Eraser, an injectable DLL that causes uninitialized stack and heap memory in its host process to be wiped over with a specific value. It is intended as a crude tool to assist in the run-time discovery of uninitialized memory usage problems by increasing the chances that the host process will raise an exception when a value in uninitialized memory is used. To use Duster, just inject it into the target process (using the DLLInject utility), or add it to AppInit_DLLs (possible but not recommended).

Duster is a quick and dirty implementation of its concept, and as such, it has a number of limitations:

Stack wiping is accomplished by overwriting all memory between the stack commit “ceiling” and ESP, whenever RtlAllocateHeap, RtlReAllocateHeap, or RtlFreeHeap is called, an exception occurs, or a system call is dispatched, which seriously limits the execution flow “granularity” with which stack wiping occurs. Additionally, system call dispatch hooking is accomplished by replacing specific “INT 2Eh” or “MOV EDX, 7FFE0300h” instructions, the first of which currently relies upon a two-byte privileged instruction which is handled specially by the exception handler hook, resulting in some overhead but mostly making it difficult to use a debugger in conjunction with Duster on Windows 2000.

Heap wiping, in addition to a limited amount of heap and argument validation, is performed whenever a heap block is allocated or freed. This is roughly a subset of the functionality provided by the Windows heap manager in debug mode, with the most significant deficiency on Duster’s part being that it does not wipe memory following a call to RtlReAllocateHeap.

The eEye Binary Diffing Suite (EBDS) is a free and open source set of utilities for performing automated binary differential analysis. This becomes very useful for reverse engineering patches as well as program updates.

The first tool is BDS, the Binary Diffing Starter from Andre Derek Protas. This tool helps reverse engineers with batch-analysis of patches by dispatching IDA with its many powerful plugins against groups of binaries. This especially comes in useful for Update Rollups or Service Packs, where automation is necessary to be able to reverse engineer the updates in a reasonable amount of time.

The second tool is DarunGrim, a code-analysis tool to actually find the distinct code-changes between two binaries. In Korean, DarunGrim translates to “difference in picture”. DarunGrim performs multiple matching techniques against functions in order to find function pairs and analyze the differences/similarities between the functions.

This allows reverse engineers to pinpoint code changes between two binaries with a graphical interface, much more rapid than “side-by-side” disassembly instances. Much like most powerful disassembly tools, DarunGrim is also using the power of IDA Pro for analysis.
