Vulnerability Note VU#146896

Gear Software CD DVD Filter driver privilege escalation vulnerability

Overview

The Gear Software CD DVD Filter driver contains a privilege escalation vulnerability, which can allow an attacker to gain SYSTEM privileges.

I. Description

Gear Software provides a driver called CD DVD Filter, which is provided by GEARAspiWDM.sys. This driver is used by multiple CD/DVD recording applications. The Gear Software CD DVD Filter driver allows unlimited calls to IoAttachDevice from a user-space application. By making multiple calls to IoAttachDevice, an attacker may be able to exploit an integer overflow in the Microsoft Windows kernel to execute code with SYSTEM privileges.

II. Impact

An attacker may be able to execute code with SYSTEM privileges.

III. Solution

Apply an update

This issue is addressed in GEAR driver version 4.001.7, which provides GEARAspiWDM.sys version 2.0.7.5. This version of the CD DVD Filter driver limits the number of IoAttachDevice calls that can be made. Please check with your software vendor for updates that contains this fixed driver. If no update is available, the stand-alone driver from GEAR may be installed.

Apple iTunes users should install iTunes 8.0, as specified in the About the security content of iTunes 8.0 document.

Symantec customers using Norton 360, Norton Ghost, Norton Save and Restore, Backup Exec System Recovery, and Symantec LiveState Recovery should apply an update, as specified in the Symantec Security Advisory SYM08-017.
