Stack-based buffer overflow in JSGCI.DLL in JustSystems Ichitaro 2005, 2006, and 2007 allows user-assisted remote attackers to execute arbitrary code via a crafted document, as actively exploited in December 2007 by the Tarodrop.F trojan.

Security readout for executives and security teams

This is an old Ichitaro document-handling vulnerability that could let an attacker run code if a user opens a malicious document. The source says it was actively exploited in December 2007 by Tarodrop.F. The main business risk is legacy Japanese office software still present on endpoints or in archives. Exposure is most likely in organizations that still run Ichitaro 2005, 2006, or 2007, or that process old Ichitaro documents on legacy workstations. The bundle does not identify server-side exposure or broader JustSystems products. Treat as high priority if legacy Ichitaro remains in use, especially on machines receiving external documents. If the software is absent, priority is limited to confirming inventory and document-handling controls. Mitigation focus: Inventory endpoints for Ichitaro 2005, 2006, and 2007 installations.; Check JustSystems or trusted advisory guidance for fixed versions or supported upgrade paths.; Remove or isolate unsupported Ichitaro versions where business use is no longer required..
