Symantec was notified of a potential Denial of Service (DoS) vulnerability in the Symantec device driver SPBBCDRV.SYS. The vulnerability is caused by a failure to validate arguments sent to NtCreateMutant and NtOpenEvent.
A potential attacker must be logged into the target computer to attempt an exploit. A successful exploit of this vulnerability could potentially allow that user to crash their computer.
Symantec engineers have verified that the vulnerability exists in the products listed in the Affected Products table above, and have provided updates to correct the problem.
Symantec is not aware of any customers impacted by this issue, or of any attempts to exploit the issue
Updating Consumer (Norton) products
Symantec Norton product users who regularly launch and run LiveUpdate should already have received an updated (non-vulnerable) version of SPBBCDRV.SYS. However, to ensure all available updates have been applied, users can run a manual LiveUpdate as follows:
- Open any installed Norton product
- Click LiveUpdate
- Run LiveUpdate until all available product updates are downloaded and installed
- A system reboot is required for this update
Symantec recommends any affected customers update their product to protect against potential attempts to exploit this issue. As part of normal best practices, Symantec recommends the following:
- Run under the principle of least privilege to limit the impact of attempted exploits.
- Limit access to trusted users.
- Keep all operating systems and applications updated with the latest vendor patches.
- Follow a multi-layered approach to security. Run both firewall and antivirus software to provide multiple points of detection and protection from inbound and outbound threats.
