Access Violation in Windows 2000 IrDA Driver Can Cause System to Restart New

A security vulnerability exists in the Windows 2000 IrDA driver which could allow a malicious user to send a specially crafted IrDA packet to a victim's system causing an access violation and forcing a reboot.

Issue

Microsoft Windows 2000 provides support for infrared-based connectivity. This support is provided through protocols developed by the Infrared Data Association (IrDA). Because of this, they are often called IrDA devices. These devices can be used to share files and printers with other IrDA-device capable systems. The software which handles IrDA devices in Windows 2000 contains an unchecked buffer in the code which handles certain IrDA packets.
