The Linksys WVC54GC NetCamPlayerWeb11gv2 ActiveX control contains a stack buffer overflow, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
The Linksys WVC54GC wireless video camera provides an ActiveX control called NetCamPlayerWeb11gv2, which is provided by the file NetCamPlayerWeb11gv2.ocx. This ActiveX control contains a stack buffer overflow in the SetSource() method.
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.
Apply an update
This vulnerability is addressed in WVC54GC firmware version 1.25. Please see the release notes for more details. Note that any client system that has installed the ActiveX control must connect to the camera and install the updated control.
