Microsoft Security Bulletin MS10-055 - Critical
Vulnerability in Cinepak Codec Could Allow Remote Code Execution (982665)
Version: 1.0
General Information
Executive Summary
This security update resolves a privately reported vulnerability in Cinepak
Codec. The vulnerability could allow remote code execution if a user opens a
specially crafted media file or receives specially crafted streaming content
from a Web site or any application that delivers Web content. An attacker
who successfully exploited this vulnerability 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 rights.
This security update is rated Critical for all supported editions of Windows
XP, Windows Vista, and Windows 7. For more information, see the subsection,
Affected and Non-Affected Software, in this section.
The security update addresses the vulnerability by correcting the manner in
which the Cinepak code decompresses media files. For more information about
the vulnerability, see the Frequently Asked Questions (FAQ) subsection for
the specific vulnerability entry under the next section, Vulnerability
Information.
Affected Software
Windows XP Service Pack 3
Windows XP Professional x64 Edition Service Pack 2
Windows Vista Service Pack 1 and Windows Vista Service Pack 2

Vulnerability Information
Cinepak Codec Decompression Vulnerability - CVE-2010-2553
A remote code execution vulnerability exists in the way the Cinepak codec
handles supported format files. This vulnerability could allow code
execution if a user opened 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.
