| Solution | Users are advised to apply the vendor patch MS09-010 |
| Vendor description | This security update resolves two publicly disclosed vulnerabilities and two privately reported vulnerabilities in Microsoft WordPad and Microsoft Office text converters. The vulnerabilities could allow remote code execution if a specially crafted file is opened in WordPad or Microsoft Office Word. |
| SophosLabs comments | Combined, all of the vulnerabilities addressed in this Microsoft update are associated with the opening of Word, RTF, WordPerfect and Write files, making it a particular target for use in malicious email attachments. Given that two of these vulnerabilities are already publicly disclosed it is quite likely that we will see attacks centred around these exploits in the coming weeks. |
