Title: Verisign i-Nav ActiveX Control Remote Buffer Overflow Vulnerability

Severity: HIGH

Description:

Verisign i-Nav ActiveX control is a software package available for Microsoft Internet Explorer and Outlook. It adds support for international domain names (IDN).

Verisign i-Nav ActiveX control is prone to a buffer-overflow vulnerability. The software fails to perform sufficient bounds-checking of user-supplied input before copying it to an insufficiently sized memory buffer.

This issue presents itself in an unspecified parameter of the 'VUpdater.Install' control.

Invoking the object from a malicious website or HTML email may trigger the condition. If the vulnerability were successfully exploited, this would corrupt process memory, resulting in arbitrary code execution. Arbitrary code would be executed in the context of the client application using the affected ActiveX control.

Affected Products:

  • VeriSign i-Nav
