----------------------------------- mimi_44 Mon 02 Apr, 2007 Vista Can Be Taken Down by an Animated Cursor ----------------------------------- Vista Can Be Taken Down by an Animated Cursor Here is some more of Bill's great work he's done for M*******t. :x mimi In what could be the most embarrassing exploit to impact Windows Vista since its commercial launch in January, security engineers at McAfee's Avert Labs confirmed today - and posted the video to prove - that the operating system can be caused to enter an interminable crash-restart-crash loop, by means of a buffer overflow triggered by nothing more than a malformed animated cursor file. t isn't even a new exploit, as researchers with eEye discovered in January 2005. At that time, Microsoft acknowledged it affected versions of the operating system from the first edition of Windows 98 through to early releases of Windows XP, though it stated at the time XP SP1 was unaffected. But apparently after researching field reports of limited attacks, Avert Labs discovered an apparently similar exploit using .ANI files impacts XP SP2 and Vista as well, as well as Windows 2000 SP4 and versions of Windows Server 2003 from the initial release through to SP1. Avert Labs stated XP SP1 and versions since were unaffected, though Microsoft warned the exploit does affect XP SP2. If both firms' accounts are correct, Microsoft may have fixed the problem with XP SP1 in 2005, and inadvertently un-fixed it sometime afterward. Avert Labs' video of the incident, posted to YouTube, shows a Vista system wherein the test file apparently trying to load the custom animated cursor. When the operating system detects a crash, it first tries to save vital data prior to a restart sequence - one of Vista's newer features. It then informs the user that Windows Explorer has crashed. But in trying to restart Explorer, the restarting crashes itself, sending Vista into a tailspin from which the only escape appears to be the off button. The mouse input routines in Windows are designed with the intention of being relatively failsafe. That's why when the system appears to hang, you can often still move your mouse pointer. As I've personally witnessed on many occasions with Windows XP, it's possible for a smaller OEM's mouse driver - often an unsigned one - to trigger a similar tailspin loop that crashes Windows Explorer repeatedly. In Windows, a lot depends on the mouse pointer's very existence. So if a customization feature can impact the mouse pointer's ability to function, the integrity of the entire system can be jeopardized. With my own systems, drivers and services that are unfriendly to one another - such as Stardock's CursorXP animation program trying to co-exist with a Synaptics Pointing Device driver on a notebook with ATI Mobility Radeon 9600 graphics - can trigger an Explorer tailspin. What I'm calling the "tailspin" is nothing new. What is very disturbing about this revelation, however, is that it can be triggered by nothing more than Microsoft's own operating system software and processes. McAfee reports this exploit is being utilized in the wild, and Microsoft today issued its boilerplate language warning users not to open e-mail attachments they don't recognize.
