The Electronic Arts SnoopyCtrl ActiveX control and plug-in contains multiple stack buffer overflows, which could allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Electronic Arts (EA.com) provides an ActiveX control and Netscape-style plug-in called SnoopyCtrl. This control, provided by NPSnpy.dll
, is included with an EA.com update package. The SnoopyCtrl ActiveX control and plug-in contains buffer overflow vulnerabilities in multiple methods and initialization parameters.
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), a remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user on a vulnerable system.
We are currently unaware of a practical solution to this problem. Please consider the following workarounds
Disable the SnoopyCtrl ActiveX control in Internet Explorer
The vulnerable ActiveX control can be disabled in Internet Explorer by setting the kill bit for the following CLSID:
{525A15D0-4938-11D4-94C7-0050DA20189B}
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\{525A15D0-4938-11D4-94C7-0050DA20189B}]
"Compatibility Flags"=dword:00000400
Disable the SnoopyCtrl plug-in in other browsers
The SnoopyCtrl plug-in can be disabled in other browsers, such as Firefox, by removing the NPSnpy.dll
file from the plugins
directory.
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” document.
Disable plug-ins
Disabling plug-ins by default can prevent exploitation of this and other plug-in vulnerabilities. This can be accomplished by configuring NoScript to Forbid other plugins
for untrusted sites.
