http://secunia.com/advisories/26729/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
ER Mapper ECW JPEG 2000 Plug-ins 8.x
http://secunia.com/product/15623/

DESCRIPTION:
Will Dormann has reported some vulnerabilities in ER Mapper ECW JPEG
2000 Plug-ins, which can be exploited by malicious people to
compromise a user's system.

The vulnerabilities are caused due to boundary errors within the
NCSViewManager.NCSView.1 (NCSView.dll) ActiveX control when
processing certain unspecified methods or properties. These can be
exploited to cause stack-based buffer overflows when a user e.g.
visits a malicious website.

Successful exploitation allows execution of arbitrary code.

SOLUTION:
Update to NCSView.dll version 3.4.0.242 included in version 8.1 of ER
Mapper ECW JPEG 2000 Plug-ins.
