| Vulnerability name/brief description | Critical Vulnerabilities in Microsoft Office Web Components Could Allow Remote Code Execution (957638) |
| CVE/CAN name | CVE-2009-0562, CVE-2009-1136, CVE-2009-1534, CVE-2009-2496 |
| Vendor threat level | Critical |
| SophosLabs threat level | Critical |
| Solution | |
| Vendor description | This security update resolves several privately reported vulnerabilities in Microsoft Office Web Components that could allow remote code execution if a user viewed a specially crafted Web page. An attacker who successfully exploited these vulnerabilities could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. |
| SophosLabs comments | As with MS09-037 this update resolves several vulnerabilities that, although privately reported can be attacked via spam emails directing users to malicious web pages. The popularity of the office software increases the liklihood of exploits being found in the wild and so SophosLabs have given this vulnerability update a threat level of critical. |
| SophosLabs testing result | N/A |
| Currently known exploits | At the time of writing SophosLabs has seen no samples of malware or web-content attempting to exploit this vulnerability. Should this situation change samples will be analyzed and we will take action as necessary. |
| First sample seen | N/A |
