No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
