Details

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 Response

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

Best Practice

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.
