Date Discovered June 10, 2008
Description Microsoft DirectX is prone to a stack-based buffer-overflow vulnerability because the application fails to perform adequate boundary checks on user-supplied data.
Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the user running the application that uses DirectX. Failed exploit attempts will result in a denial-of-service condition.
NOTE: Supported editions of Windows Server 2008 are not affected if installed using the Server Core installation option.

Run all software as a nonprivileged user with minimal access rights. To limit the potential damage that a successful exploit may achieve, run all nonadministrative software as a regular user with the least amount of privileges required to successfully operate.
Do not accept or execute files from untrusted or unknown sources. To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.
Do not follow links provided by unknown or untrusted sources. Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
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.
Microsoft has released an advisory along with fixes. Please see the references for details.
