Detailed Description |
| Business Impact: |
This bulletin covers three vulnerabilities in Microsoft Internet Explorer. The most critical problem is an FTP client vulnerability that can be exploited by a malformed response from a malicious server. It is easy to direct web browsers to an FTP URL on a malicious site, so this issue should be taken seriously. The other two issues relate to the instantiation of COM objects in IE that were not designed to be instantiated in IE, and create exploitable memory corruption when run. A denial of service POC for one of these issues was posted publicly in August, but it only impacts systems that support Kanji. Other impacted objects are more common place. IE7 provides protection from the COM object vulnerabilities by default due to a new opt-in feature for ActiveX controls. |

| Technical Description: |
Microsoft Internet Explorer could allow a remote attacker to execute arbitrary code on a victim's system, caused by improper handling of FTP responses by Internet Explorer's built-in FTP client. If a remote attacker could persuade a victim to visit a malicious FTP server using Internet Explorer, the attacker could exploit this vulnerability to execute arbitrary code on the system with the privileges of the victim. |
| Remediation instructions: |
Patches for these issues have been released by Microsoft. See References for details. |
