This security update resolves vulnerabilities in Microsoft Windows. The more severe of the vulnerabilities could allow remote code execution if a user opens a specially crafted .pdf file. An attacker who successfully exploited the vulnerabilities could cause arbitrary code to execute in the context of the current user. However, an attacker would have no way to force a user to open a specially crafted .pdf file.
