It is available as an ActiveX control for IE-based browsers, and as a Netscape style plug-in for other browsers such as Firefox and Safari. The LizardTech DjVu Browser Plug-in contains multiple 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 the web browser to crash.","resolution":"Apply an update\nThis issue is resolved in the DjVu Browser Plug-in version 6.1.1.","workarounds":"Disable the DjVu ActiveX control in Internet Explorer The vulnerable ActiveX control can be disabled in Internet Explorer by setting the kill bit for the following CLSID: {0e8d0700-75df-11d3-8b4a-0008c7450c4a} More information about how to set the kill bit is available in Microsoft Support Document 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\\{0e8d0700-75df-11d3-8b4a-0008c7450c4a}] \"Compatibility Flags\"=dword:00000400\nDisable 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.
