This vulnerability isn’t being exploited in the wild currently, but if it follows the trends of similar vulnerability releases, it is expected with high confidence that it will be targeted in the near future. For the Microsoft Office Memory Corruption Vulnerability to being successfully exploited, only basic user interaction, such as opening a spam email or clicking on a malicious link, is required. This vulnerability existed for 17 years before discovery; this is a reminder that even long-standing, trusted software can be subject to security flaws.
