This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution when Windows improperly handles objects in memory. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. To exploit the vulnerability, a domain-authenticated attacker could make a specially crafted NetLogon request to a domain controller. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights. This update corrects how Windows handles objects in memory to prevent corruption.
