Original Release date: 09 Sep 2004 | Last revised: 09 Sep 2004


There is a vulnerability in the Mac OS X CoreFoundation framework that could allow a local attacker to gain elevated privileges.


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.


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.
