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.

This issue is a candidate for inclusion in the Common Vulnerabilities and Exposures (CVE) list (<http://cve.mitre.org>), which standardizes names for security problems. The CVE initiative has assigned CVE-2007-1476 to this issue.
SecurityFocus has assigned BID 22977 to this vulnerability.
