Who is Vulnerable?
Vulnerability Description A buffer overflow vulnerability exists in the way Microsoft Word processes word documents. The vulnerability is the result of an infinite loop. A remote attacker can exploit this vulnerability by enticing the target user to open a crafted Word document, potentially causing arbitrary code to be injected and executed in the security context of the current user. In an attack scenario, where arbitrary code is injected and executed on the target machine, the behavior of the target is dependent on the intention of the malicious code. If code execution is not executed successfully, the vulnerable application may terminate as a result of the attack attempt. If unexpected termination of the vulnerable application is the sole result of an attack, there is no impact to the overall operation of the target host. It is, however, possible to lose all unsaved data due to the abnormal termination.
