ISSUES

Details
Boon Seng Lim notified Symantec of a vulnerability in SAVRT.SYS which could allow a malicious user to use the output buffer of DeviceIOControl() to overwrite kernel addresses because the address space of the output buffer was not properly validated. A successful exploit could potentially allow a local attacker to execute code of their choice with elevated privileges, or to crash the system.

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-2006-3455 to this issue
