Microsoft Data Access Components are prone to a remote memory-corruption vulnerability.
An attacker can exploit this issue by enticing an unsuspecting user to view a malicious webpage.
Successful exploits will allow the attacker to execute arbitrary code within the context of the application. Failed exploit attempts will result in a denial-of-service condition.
NOTE: This issue was originally reported at the 2010 CanSecWest conference as part of the Pwn2Own contest. It was also previously documented in BID 38951 (Microsoft Internet Explorer Unspecified Remote Code Execution Vulnerabilities) but has been moved here to better document it.

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.
Do not follow links provided by unknown or untrusted sources.
Attackers could exploit this vulnerability by enticing a user to visit a malicious website. Do not follow links provided by sources of questionable integrity.
Set web browser security to disable the execution of script code or active content.
Disable support for script code and active content within a client browser to reduce the chances of a successful exploit. Note that this mitigation tactic might adversely affect legitimate websites that rely on the execution of browser-based script code.
Implement multiple redundant layers of security.
Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.
Vendor updates are available. Please see the references for more information.
