Microsoft Internet Explorer is prone to a memory-corruption vulnerability when instantiating certain COM objects. Successfully exploiting this issue allows remote attackers to execute arbitrary machine code in the context of the affected application. This facilitates the remote compromise of affected computers. Internet Explorer 7 on Microsoft Vista is not affected by this issue; Internet Explorer 7 on other Windows versions is affected only if COM objects have been enabled by the ActiveX opt-in feature. This BID is similar to the one described in BID 15827 (Microsoft Internet Explorer COM Object Instantiation Memory Corruption Vulnerability), but it affects a different set of COM objects.

Do not follow links provided by unknown or untrusted sources.
Users should be wary of visiting sites of questionable integrity or following links provided by unfamiliar or suspicious sources.
Set web browser security to disable the execution of script code or active content.
Disabling scripting and active content in the Internet Zone may limit exposure to this and other vulnerabilities.
Implement multiple redundant layers of security.
Various memory-protection schemes (such as non-executable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.
Run all software as a nonprivileged user with minimal access rights.
Run the web client as an unprivileged user with minimal access rights. This will limit the impact of latent vulnerabilities.
Microsoft has released an advisory along with fixes to address this issue. Please see the references for more information.
