Vulnerability Note VU#446012
Microsoft Word object pointer memory corruption vulnerability
Overview
A memory corruption vulnerability in Microsoft Word could allow a remote attacker to execute arbitrary code with the privileges of the user running Word.
Description
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. 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. |
Impact
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. |
Solution
Apply a patch from Microsoft |
Do not open untrusted Word documents
In most cases, Windows will call Word to open a document even if the document has an unknown file extension. For example, if document.qwer contains the correct file header information, Windows will open document.qwer with Word. Filtering for common extensions (e.g., .doc, .dot, .rtf) may not detect all Word documents. |
