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). http://www.justsystems.com/jp/info/pd7004.html Provided and/or discovered by: Hiroshi Ukai, Fourteenfourty Research Institute Changelog: 2007-10-30: Added CVE reference.
