Description

The version of GEAR Software's CD DVD Filter kernel driver (GEARAspiWDM.sys) on the remote host contains an insecure method that allows a local user to make an unlimited number of calls to 'IoAttachDevice' from user-land, thereby enabling him to exploit a local privilege escalation flaw in the Microsoft Windows kernel in the 'IopfCompleteRequest' function.

Note that this driver may have been installed as part of a third-party application such as Apple iTunes, Norton 360, Norton Ghost, Norton Save and Restore, Backup Exec System Recovery, or Symantec LiveState Recovery.
