| Vendor threat level | Critical |
| SophosLabs threat level | Medium |
| Solution | Users are advised to apply the vendor patch for MS09-027 . |
| Vendor description | This security update resolves two privately reported vulnerabilities that could allow remote code execution if a user opens a specially crafted Word file. An attacker who successfully exploited either vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. |
| SophosLabs comments | Microsoft Word binary format files are often used maliciously to exploit an unpatched vulnerability in Microsoft Word to drop malicious Windows PE executable files. Security update should be applied as soon as possible, especially by Microsoft Office Word 2000 users. Both of the disclosed vulnerabilities are buffer overflow vulnerabilities and Sophos customers are advised to use Sophos Buffer Overflow protection functionality to mitigate the threat. |
| SophosLabs testing result | N/A |
