Overview
There is a vulnerability in the Mac OS X CoreFoundation framework that could allow a local attacker to gain elevated privileges.
Description
The Core Foundation framework (CoreFoundation.framework) is designed to allow code and data sharing between frameworks, libraries, and applications in different environments and layers. It includes the CFPlugIn, which provides a standard architecture for application extensions. There is a vulnerability in the way CoreFoundation loads user-supplied libraries for applications using the CFPlugIn facilities. |
Impact
An authenticated local attacker could cause an application using the CoreFoundation CFPlugIn facilities to load a user-supplied library. Exploitation of this vulnerability on privileged applications could allow an attacker to gain elevated privileges. |
Solution
Apple has released a patch to address this vulnerability. For further details, please see the Apple Security Advisory (Security Update 2004-09-07). |
