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.
