Description

The remote host contains an ActiveX control, 'VUpdater.Install', associated with Verisign I-Nav, which provides support for Internationalized Domain Names in Microsoft Internet Explorer, Outlook and Outlook Express that reportedly contains a buffer overflow vulnerability that arises when processing CAB files. A remote attacker may be able to leverage this issue to specify an arbitrary executable to be run subject to the privileges of the current user.
