Synopsis

The remote Windows host is affected by an information disclosure vulnerability.

Description

The remote Windows host is missing security update KB4014793. It is, therefore, affected by a remote code execution vulnerability in Windows WordPad due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted file, to execute arbitrary code.

Solution

Apply security update KB4014793.
