Microsoft Security Bulletin MS06-013

Industry Reference:CVE-2006-1186
Protection Provided by:
Who is Vulnerable? Internet Explorer 5.01 SP4, 6 SP1; and prior service packs
Vulnerability Description Microsoft Internet Explorer allows instantiation of COM objects that are not designed for use in the browser. This may allow a remote attacker to execute arbitrary code or crash the browser.

COM (Component Object Model) objects are shared functions that can be used by applications to perform tasks. These functions are commonly implemented as dynamic link libraries (DLL). Any application can instantiate a COM object without knowing many details about its behavior or requirements. Once a malicious component (DLL file) is started by a trusted application, this object can cause the application to perform unauthorized functions.
Update/Patch AvaliableApply patches:
