Microsoft Security Bulletin MS11-085 - Important
Vulnerability in Windows Mail and Windows Meeting Space Could Allow Remote
Code Execution (2620704)
Published: Tuesday, November 08, 2011
This security update resolves a privately reported vulnerability in Microsoft
Windows. The vulnerability could allow remote code execution if a user opens a
legitimate file (such as an .eml or .wcinv file) that is located in the same
network directory as a specially crafted dynamic link library (DLL) file. Then,
while opening the legitimate file, Windows Mail or Windows Meeting Space could
attempt to load the DLL file and execute any code it contained. For an attack
to be successful, a user must visit an untrusted remote file system location or
WebDAV share and open a legitimate file (such as an .eml or .wcinv file) from
this location that is then loaded by a vulnerable application.
This security update is rated Important for all supported editions of Windows
Vista; is rated Moderate for all supported editions of Windows Server 2008; and
is rated Low for all supported editions of Windows 7 and Windows Server 2008 R2.

Windows Mail Insecure Library Loading Vulnerability - CVE-2011-2016
A remote code execution vulnerability exists in the way that Windows Mail and
Windows Meeting Space handle the loading of DLL files. An attacker who
successfully exploited this vulnerability could take complete control of an
affected system. An attacker could then install programs; view, change, or delete
data; or create new accounts with full user rights. 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.
