Justsystem » Ichitaro : Security Vulnerabilities, CVEs, Published In 2007 (Code Execution)

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. NOTE: some of these details are obtained from third party information.

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.

Unspecified vulnerability, possibly a buffer overflow, in Justsystem Ichitaro 2007 and earlier allows remote attackers to execute arbitrary code via a modified document, as actively exploited in August 2007 by malware such as Tarodrop.D (Tarodrop.Q), a different vulnerability than CVE-2006-4326, CVE-2006-5424, CVE-2006-6400, and CVE-2007-1938.
