Microsoft Security Bulletin MS12-004 - Critical
Vulnerabilities in Windows Media Could Allow Remote Code Execution
Published Date: January 10, 2012
This security update resolves two privately reported vulnerabilities in
Microsoft Windows. The vulnerabilities could allow remote code execution if a
user opens a specially crafted media file. An attacker who successfully
exploited the vulnerabilities could gain the same user rights as the local
user. Users whose accounts are configured to have fewer user rights on the
system could be less impacted than users who operate with administrative user
This security update is rated Critical for all supported editions of Windows
XP, Windows Server 2003, Windows Vista, and Windows Server 2008; and
Important for all supported editions of Windows Media Center TV Pack for
Windows Vista, Windows 7, and Windows Server 2008 R2 for Itanium-based Systems.
For more information, see the subsection, Affected Software, in this section.

MIDI Remote Code Execution Vulnerability - CVE-2012-0003
A remote code execution vulnerability exists in Windows Media Player. An
attacker could exploit this vulnerability by constructing a specially crafted
MIDI file that could allow remote code execution when played using Windows
Media Player. An attacker who successfully exploited this vulnerability could
take complete control of an affected system.
DirectShow Remote Code Execution Vulnerability - CVE-2012-0004
A remote code execution vulnerability exists in the way that Windows handles
media files. This vulnerability could allow remote code execution if a user
opens a specially crafted media file. If a user is logged on with
administrative user rights, 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.
