Microsoft Security Bulletin MS12-080 - Critical

Vulnerabilities in Microsoft Exchange Server Could Allow Remote Code Execution
(2784126)

Published Date: December 11, 2012 | Updated Date: Unspecified

Version: 1.0

General Information

Executive Summary

This security update resolves publicly disclosed vulnerabilities and one
privately reported vulnerability in Microsoft Exchange Server. The most severe
vulnerabilities are in Microsoft Exchange Server WebReady Document Viewing and
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 is running in the LocalService account. The
LocalService account has minimum privileges on the local computer and presents
anonymous credentials on the network.

This security update is rated Critical for all supported editions of Microsoft
Exchange Server 2007 and Microsoft Exchange Server 2010. 

Affected Software

Microsoft Exchange Server 2007 Service Pack 3 
Microsoft Exchange Server 2010 Service Pack 1 
Microsoft Exchange Server 2010 Service Pack 2 

Vulnerability Information

Oracle Outside In Contains Multiple Exploitable Vulnerabilities - CVE-2012-3214
and CVE-2012-3217

Remote code execution vulnerabilities exist in Microsoft Exchange Server
through the WebReady Document Viewing feature. These vulnerabilities could
allow remote code execution as the LocalService account if a user views a
specially crafted file through Outlook Web Access in a browser. An attacker who
successfully exploited the vulnerabilities could run code on the affected
server, but only as the LocalService account. The LocalService account has
minimum privileges on the local computer and presents anonymous credentials on
the network.

RSS Feed May Cause Exchange DoS Vulnerability - CVE-2012-4791

A denial of service vulnerability exists in Microsoft Exchange Server when
Exchange improperly handles RSS feeds. The vulnerability could cause the
Information Store service on the affected system to become unresponsive until
the process is forcibly terminated. This unresponsive condition could cause
Exchange databases to dismount, and potentially lead to corruption of databases,
affecting user mailboxes.
