VERIFY ADVISORY:
http://secunia.com/advisories/30598/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
BackWeb BackWeb Lite Install Runner ActiveX Control 8.x
http://secunia.com/product/19029/

DESCRIPTION:
Will Dormann has reported some vulnerabilities in BackWeb Lite
Install Runner ActiveX Control, which can be exploited by malicious
people to compromise a user's system.

The vulnerabilities are caused due to boundary errors in the BackWeb
Lite Install Runner ActiveX control (LiteInstActivator.dll) when
handling certain unspecified methods. These can be exploited to cause
stack-based buffer overflows when a user e.g. is tricked into visiting
a malicious website.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities reportedly affects versions prior to 8.1.1.87.

SOLUTION:
Update to version 8.1.1.87.

MS08-032 sets the kill-bit for the affected ActiveX control.
