Detail

Revision Note: V1.0 (April 12, 2011): Bulletin published.Summary: This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability in Microsoft Office. The vulnerabilities could allow remote code execution if a user opens a specially crafted Office file or if a user opens a legitimate Office file that is located in the same network directory as a specially crafted library file. An attacker who successfully exploited either of these vulnerabilities could gain the same user rights as the logged on 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.

Open Source Vulnerability Database (OSVDB)

Id Description
71768 Microsoft Office Graphic Object Parsing Remote Code Execution

Microsoft Office and Open XML File Format Converter for Mac contain a flaw related to the office drawing file format. The issue is triggered when an error occurs during parsing of shape data and freeing used elements without removing references to them. This may allow a context-dependent attacker using a crafted shape data in the Office drawing file format to execute arbitrary code.
71767 Microsoft Office Path Subversion Arbitrary DLL Injection Code Execution

Microsoft Office is prone to a flaw in the way it loads dynamic-link libraries (DLL). The program uses a fixed path to look for specific files or libraries. This path includes directories that may not be trusted or under user control. By placing a custom version of the file or library in the path, the program will load it before the legitimate version. This allows an attacker to inject custom code that will be run with the privilege of the program or user executing the program. This can be done by tricking a user into opening a .docx file from the local file system or a USB drive in some cases. This attack can be leveraged remotely in some cases by placing the malicious file or library on a network share or extracted archive downloaded from a remote source.
