The eBay Enhanced Picture Services (EPUImageControl Class) ActiveX control contains a buffer overflow vulnerability. This may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
ActiveX is a technology that allows programmers to create reusable software components that can be incorporated into applications to extend their functionality. Internet Explorer is a common Windows application that makes use of ActiveX controls.
eBay has provided the following steps to determine if the Enhanced Picture Services ActiveX control is installed:
1. Launch Internet Explorer
2. Select Tools -> Internet Options
3. Click "Settings..." button in the "Temporary Internet files" group
4. Click on "View Objects..."
5. This will launch Windows Explorer. In the Program File column you
should see "EPUImageControl Class" . If you don't see this file, then the
ActiveX is not installed. Otherwise right click on name, select the Version
tab to see the ActiveX version
The eBay Enhanced Picture Services ActiveX control version 184.108.40.206 and earlier contain a buffer overflow vulnerability.
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash.
