Summary: This security update resolves a vulnerability in Windows Uniscribe. The vulnerability could allow remote code execution if a user visits a specially crafted website or opens a specially crafted document. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. This security update addresses the vulnerabilities by correcting how the Windows Uniscribe handles objects in the memory.
