CVE-2005-1980: Distributed Transaction Controller in Microsoft Windows allows remote servers to cause a denial of service...

Security readout for executives and security teams

This is an old Microsoft Windows Distributed Transaction Controller denial-of-service issue. A remote system can send a crafted Transaction Internet Protocol message that may cause MSDTC to hang by repeatedly connecting to a target IP and port after an error. The available bundle does not show code execution or data theft impact. Likely exposure is Windows systems where MSDTC is installed, enabled, and reachable by remote systems using TIP. The bundle’s affected-product metadata is incomplete, so confirm affected Windows versions against Microsoft MS05-051 and local asset inventory. Prioritize as a legacy Windows availability risk. It is most urgent where old Windows systems still support transaction processing or expose MSDTC across network boundaries. Absence from KEV lowers urgency, but unsupported systems may remain vulnerable. Mitigation focus: Review Microsoft MS05-051 for affected versions and vendor remediation.; Apply the relevant Microsoft security update where applicable.; Inventory Windows hosts running or exposing MSDTC/TIP..
