Motive Communications ActiveUtils EmailData ActiveX control stack buffer overflows

Description

### Overview The Motive Communications ActiveUtils EmailData ActiveX control contains multiple stack buffer overflows, which could allow an attacker to execute arbitrary code on a vulnerable system. ### Description Motive Communications ActiveUtils is a software package used by multiple ISPs to provide service activation, system configuration, and other diagnostics capabilities. The file `ActiveUtils.dll` provides multiple ActiveX controls that provide this functionality. The ActiveX control `ActiveEmailTest.EmailData` contains multiple stack buffer overflow vulnerabilities. --- ### 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. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash. --- ### Solution **Apply an update** Please see the Motive [Security Bulletin](<http://www.motive.com/securitybulletin_08122007.asp>). This vulnerability is also addressed by Microsoft Security Bulletin [MS07-045](<http://www.microsoft.com/technet/security/Bulletin/MS07-045.mspx>). This update sets the kill bit for the vulnerable control. --- **Disable the Motive EmailData ActiveX control in Internet Explorer** The vulnerable Motive EmailData ActiveX controls can be disabled in Internet Explorer by setting the kill bit for the following CLSID: `{D256B2D9-9C58-445A-8C38-C3AAA84EF137}` More information about how to set the kill bit is available in [Microsoft Support Document 240797](<http://support.microsoft.com/kb/240797>). Alternatively, the following text can be saved as a `.REG` file and imported to set the kill bit for this control: `Windows Registry Editor Version 5.00` `[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{D256B2D9-9C58-445A-8C38-C3AAA84EF137}]` `"Compatibility Flags"=dword:00000400` **Disable ActiveX** 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](<http://www.us-cert.gov/reading_room/securing_browser/#Internet_Explorer>)" document. --- ### Vendor Information 747233 Filter by status: All Affected Not Affected Unknown Filter by content: __ Additional information available __ Sort by: Status Alphabetical Expand all **Javascript is disabled.
