Microsoft · Office Word · CVE-2006-4534
**Name of the Vulnerable Software and Affected Versions**
Microsoft Word versions 2000 through 2003
Microsoft Office version 2003
**Description**
The issue allows remote user-assisted attackers to execute arbitrary code via unspecified vectors involving a crafted file, resulting in a malformed stack. This could be exploited when Microsoft Word opens a specially crafted file, which might be included as an e-mail attachment or hosted on a malicious web site. Malware such as Trojan.Mdropper.Q, Mofei, and Femo have been known to exploit this issue.
**Recommendations**
For Microsoft Word versions 2000 through 2003, update to a version that is not affected by this issue.
For Microsoft Office version 2003, update to a version that is not affected by this issue.
As a temporary workaround, consider avoiding the use of Microsoft Word to open files from untrusted sources until a patch is available.
Restrict access to e-mail attachments and malicious web sites to minimize the risk of exploitation.
