Technical details
A heap-based buffer overflow in Microsoft Office Word's document parsing functionality allows remote code execution when processing a specially crafted Word file. The vulnerability can be triggered via network delivery of a malicious document without requiring user authentication, though user interaction (opening the document) is likely needed. Successful exploitation grants the attacker code execution at the privilege level of the user running Word.
