Details
Symantec was notified of a potential denial of service vulnerability in the 
device driver SYMTDI.SYS. A specially crafted IRP sent to an IOCTL handler 
function could allow memory to be overwritten because the address space was not 
properly validated in some versions of the driver. A potential attacker must be 
logged into the 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 section above, and have provided updates for 
all affected products. Consumer (Norton) products can be updated by running 
LiveUpdate.  Symantec AntiVirus Corporate Edition customers can obtain the 
update from the Symantec web site. 

Symantec is not aware of any customers impacted by this issue, or of any 
attempts to exploit the issue.
