Buffer overflow in JustSystems JSFC.DLL, as used in multiple JustSystems products such as Ichitaro, allows remote attackers to execute arbitrary code via a crafted .JTD file.
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.
