DRM Hole Sets Patch Speed Record For Microsoft

puppetman writes "Wired columnist Bruce Schneier has an article up called 'Quickest Patch Ever', about a patch that was issued within three days to fix a vulnerability in Windows Digital Rights Management (DRM)." From the article: "Now, this isn't a 'vulnerability' in the normal sense of the word: digital rights management is not a feature that users want. Being able to remove copy protection is a good thing for some users, and completely irrelevant for everyone else. No user is ever going to say: 'Oh no. I can now play the music I bought for my PC on my Mac. I must install a patch so I can't do that anymore.' But to Microsoft, this vulnerability is a big deal. It affects the company's relationship with major record labels. It affects the company's product offerings. It affects the company's bottom line. Fixing this 'vulnerability' is in the company's best interest; never mind the customer."

      Dear Windows Media Licensee,

      On August 25th, 2006, Engadget.com reported on a software tool that would allow consumers to decrypt WMDRM protected content. In response, on August 28, 2006, Microsoft released an update to the individualized blackbox component (IBX) designed to ensure that client applications using the Windows Media Format SDK version 9.5 who individualize to this latest version are robust against a new circumvention tool.

      This update is not yet available for the Windows Media Format 9 Series FSDK or for users of Windows XP Media Center Edition 2005 Update Rollup 2.

      Consumers are not at risk in any way. Content services can require that the updates be present in order to issue licenses by following the instructions below. Please note that the version number of IBX was not incremented as part of these updates to avoid delaying the release of these critical breach mitigations. Consequently, the only way to determine if the update is installed is to query the build number of the IBX. This requires code executing on the client.

      To determine the build number of the IBX:

      1. Ensure the PC is running the August 2005 update to Windows Media DRM. See the attached white paper for details.
      2. Determine the path of the WMDRM folder. The path is stored in the registry at HKEY_LOCAL_MACHINE\Software\Microsoft\DRM\DataPath
      3. Identify the file name of the latest IBX. If the machine has been individualized only once, the IBX file name will be indivbox.key. Otherwise, the IBX file name is in the form indivbox_xxx.key, where xxx are digits 0-9. The file name with the greatest value of xxx will be the latest IBX.
      4. Call GetFileVersionInfo() to retrieve the build version of the file identified in step 3. See [link].
      5. If the IBX file version is 11.0.5497.6285 or greater, then the updated IBX is installed
