A memory corruption vulnerability in Microsoft Word could allow a remote attacker to execute arbitrary code with the privileges of the user running Word.
Microsoft Word contains a memory corruption vulnerability. According to Microsoft Security Bulletin MS06-027:
_When a user opens a specially crafted Word document using a malformed object pointer, it may corrupt system memory in such a way that an attacker could execute arbitrary code. _
Office documents can contain embedded objects. For example, a malicious Word document could be embedded in an Excel or PowerPoint document. Office documents other than Word documents could be used as attack vectors.
For more information, including a complete list of affected software refer to Microsoft Security Bulletin MS06-027
Note that working exploit code is available for this vulnerability.
By convincing a user to open a specially crafted Word document, an attacker could execute arbitrary code with the privileges of the user running Word. If the user is logged in with administrative privileges, the attacker could take complete control of a vulnerable system.
