| Solution | |
| Vendor description | This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if an attacker set up a malicious Web page that invokes the Indexing Service through a call to its ActiveX component. This call could include a malicious URL and exploit the vulnerability, granting the attacker access to the client system with the privileges of the user browsing the Web page. 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 | This security update addresses the vulnerability by modifying the way that the Indexing Service ActiveX control processes URLs. This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. If successfully exploited, an attacker could then install programs or view, change, or delete data; or create new accounts with full user rights. |
| SophosLabs testing result | N/A |
| Currently known exploits | At the time of writing SophosLabs have not observed any malware 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 |
| Discovery date | 13 October 2009 |
