Exploit Shield vs DirectShow Posted by Sean @ 08:49 GMT

We posted a link to Microsoft Advisory 971778 / CVE-2009-1537 last week.

The advisory details a vulnerability in Microsoft's DirectShow, quartz.dll, affecting QuickTime parsing. (Not a QuickTime vulnerability.) Microsoft has reported some use of an exploit in the wild.

An analyst from our Exploit Shield team, Victor, tested a working sample against our Exploit Shield technology.

His efforts can be seen below, click the image for a larger view.

P.S. And just so you know, there is ALSO a QuickTime vulnerability that's been patched. See our vulnerability description for details. Update your QuickTime to version 7.6.2.

Updated to add: There's also an advisory for iTunes so you can get your QuickTime update along with iTunes 8.2.

Our vulnerability description has details.
