Microsoft Word Malformed Data Structures Code Execution Vulnerability

Microsoft Word is prone to a remote code-execution vulnerability.

An attacker could exploit this issue by enticing a victim to open a malicious Word file. If the attack is successful, the attacker may be able to execute arbitrary code in the context of the currently logged-in user.

This issue is being actively exploited in the wild in limited targeted attacks.

Note that this issue is distinct from BID 21451 (Microsoft Word Malformed String Arbitrary Remote Code Execution Vulnerability).

Update - February 1, 2007: A new variant of this issue has been detected in the wild. Please see the references for more information about this variant, which is referred to as Trojan.Mdropper.X. Note that Trojan.Mdropper.X was previously thought to be targeting a new vulnerability that was described in BID 22328 (Microsoft Word 2003 Unspecified Code Execution Vulnerability). However, further analysis and reports have revealed that it is not distinct from this vulnerability. BID 22328 has been retired.

Microsoft Word Malformed Data Structures Code Execution Vulnerability

This vulnerability is known to be actively exploited in the wild.

December 14, 2006: A proof-of-concept document '12122006-djtest.doc' that was originally thought to be exploiting this issue is being removed from this record because the '12122006-djtest.doc' file actually exploits a different vulnerability. Please see BID 21589 (Microsoft Word Code Execution Vulnerability) for more information.

February 1, 2007: A new variant named Trojan.Mdropper.X that is known to be exploiting this issue in the wild has been detected.
