The vulnerability affects all supported releases of Microsoft Windows, excluding Windows Server 2003. The vulnerability could allow remote code execution if a user opens a specially crafted Microsoft Office file that contains an OLE object. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. The attack requires user interaction to succeed on Windows clients with a default configuration, as User Account Control (UAC) is enabled and a consent prompt is displayed.
Recommendation: Do not open Microsoft PowerPoint files that you receive from untrusted sources or that you receive unexpectedly from trusted sources. This vulnerability could be exploited when a user opens a specially crafted file.
