MS16-040: Description of the security update for Microsoft XML core services: April 12, 2016

Summary

This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user clicks a specially crafted link that could allow an attacker to run malicious code remotely to take control of the user’s system. However, in all cases an attacker would have no way to force a user to click a specially crafted link. An attacker would have to convince a user to click the link, typically by way of an enticement in an email or Instant Messenger message.

To learn more about the vulnerability, see Microsoft Security Bulletin MS16-040.
