Microsoft Windows NT 4.0, Windows 2000, Windows XP, and Windows Small Business Server 2003 allow remote attackers to cause a denial of service (IP stack hang) via a continuous stream of packets on TCP port 135 that have incorrect TCP header checksums and random numbers in certain TCP header fields, as demonstrated by the Achilles Windows Attack Tool. NOTE: the researcher reports that the Microsoft Security Response Center has stated "Our investigation which has included code review, review of the TCPDump, and attempts on reproing the issue on multiple fresh installs of various Windows Operating Systems have all resulted in non confirmation.

Security readout for executives and security teams

This CVE describes a reported denial-of-service condition against older Microsoft Windows systems. The claim is that sustained malformed traffic to TCP port 135 could hang the IP stack. The record also notes Microsoft reportedly could not confirm the issue after investigation, so business urgency depends on whether these systems and exposures still exist. Exposure is limited to environments running the named Windows versions with TCP port 135 reachable from untrusted networks. The source bundle does not provide confirmed affected CPEs, supported configurations, patch status, or reproducible vendor confirmation. Treat as a targeted legacy exposure question, not a confirmed emergency. If no named Windows systems expose TCP/135, priority is low. If critical systems match the report and are reachable, reduce exposure and monitor availability while seeking vendor-confirmed guidance. Mitigation focus: Check Microsoft guidance for any confirmed advisory, workaround, or clarification.; Inventory systems matching the named Windows versions.; Restrict untrusted network access to TCP port 135 where operationally feasible..
