Multiple buffer overflows in the rich text processing functionality in JustSystems Ichitaro 2004 through 2007, 11 through 13, and other versions allow remote attackers to execute arbitrary code via a long (1) pard field or (2) font name in the fcharset0 field, which is not properly handled in (a) JSTARO4.OCX; or (3) a long title, which is not properly handled by (b) TJSVDA.DLL.

Security readout for executives and security teams

CVE-2007-5687 is a legacy document-parsing flaw in JustSystems Ichitaro. A malicious rich-text document could crash vulnerable processing code or run code on the user’s machine. Business urgency depends on whether the organization still has Ichitaro 2004-2007, versions 11-13, or related legacy installations. Exposure is most likely on legacy Japanese office environments, archives, or endpoints where affected Ichitaro versions remain installed and users can open untrusted rich-text documents. Treat this as a legacy endpoint risk with potentially high impact but narrow exposure. Prioritize discovery first; escalate remediation if Ichitaro remains installed on machines handling external documents. Mitigation focus: Inventory endpoints for affected Ichitaro versions and related components.; Review JustSystems advisory pd7004 for vendor remediation guidance.; Remove or isolate unsupported Ichitaro installations where business use is no longer required..
