Technical Information

Brief overview of the risk:
If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Detailed Information on the risk:
This bulletin covers six different remote code execution vulnerabilities in Microsoft Word, four of which are being exploited in the wild with the MDropper trojan. Three of these made headlines in early December when exploits and proof of concept code started circulating in the wild one after the other in rapid succession. The fourth was discovered in late January. Network managers should have this patch on the top of their todo lists.Further information on this exploit is available at : MS07-014
