DESCRIPTION

This security update resolves three publicly disclosed vulnerabilities in Microsoft Exchange Server. The vulnerabilities exist in the WebReady Document Viewing and Data Loss Prevention features of Microsoft Exchange Server. The vulnerabilities could allow remote code execution in the security context of the transcoding service on the Exchange server if a user previews a specially crafted file using Outlook Web App (OWA). The transcoding service in Exchange that is used for WebReady Document Viewing uses the credentials of the LocalService account. The Data Loss Prevention feature hosts code that could allow remote code execution in the security context of the Filtering Management service if a specially crafted message is received by the Exchange server. The Filtering Management service in Exchange uses the credentials of the LocalService account. The LocalService account has minimum privileges on the local system and presents anonymous credentials on the network.
