Overview
The BusinessObjects RptViewerAX ActiveX control contains a stack buffer overflow, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Description
BusinessObjects 6.5 includes an ActiveX control called RptViewerAX, which is provided by RptViewerAX.dll. This ActiveX control is marked as Safe for Scripting and Safe for Initialization, which means that they can be controlled by a web page in Internet Explorer. The RptViewerAX ActiveX control is vulnerable to stack buffer overflow. |
Impact
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user. |
Solution
Apply an update According to the vendor: |
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{B20D9D6A-0DEC-4d76-9BEF-175896006B4A}] "Compatibility Flags"=dword:00000400 Disabling ActiveX controls in the Internet Zone (or any zone used by an attacker) appears to prevent exploitation of this and other ActiveX vulnerabilities. Instructions for disabling ActiveX in the Internet Zone can be found in the "Securing Your Web Browser" document. |
