DESCRIPTION:
Hiroshi Ukai has reported some vulnerabilities in Ichitaro, which can
be exploited by malicious people to compromise a user's system.

1) Two boundary errors within JSTARO4.OCX can be exploited to cause
stack-based buffer overflows when a specially crafted document is
opened, e.g. via the browser plug-in.

2) A boundary error within TJSVDA.DLL can be exploited to cause a
buffer overflow when a specially crafted document is opened, e.g. via
the browser plug-in.

Successful exploitation allows execution of arbitrary code.

SOLUTION:
The vendor has released updates (please see vendor advisory for
details).
