---
The Services and Field Security Support Team is sending this alert you of a possible change in the threat environment surrounding MS04-007. Specifically, we are aware that sample exploit code (also known as "Proof of Concept" code) has been made publicly available for the vulnerability addressed by MS04-007. This sample code only demonstrates a denial of service attack, it does not demonstrate remote code execution. In addition, we are aware of general increased activity around this vulnerability. We are not currently aware of any published sample exploit code that demonstrates remote arbitrary code execution.

We are NOT aware of any active attacks against the vulnerability addressed by MS04-007.

However, the presence of sample exploit code and heightened activity around this vulnerability does potentially change the threat environment because the existence of sample code can make it easier for an active exploit to be developed and released. We are therefore urging customers to immediately apply the security update to protect themselves from any possible exploits which may be developed.
