Technical details
A heap-based buffer overflow exists in Microsoft Office Word's document parsing logic. An attacker can craft a malicious Office document that, when opened by a user, triggers the overflow to execute arbitrary code with the privileges of the user running Word. The vulnerability requires user interaction (opening a document) but can be delivered via network means.
