Discussion
Apple CoreFoundation Privileged Plug-In Execution Vulnerability
It is reported that bundles using CoreFoundation can be made to automatically load plug-in executables using the CFPlugIn feature. This is a security vulnerability allowing for local privilege escalation as malicious executable plug-ins can be loaded by a privileged application. At this time, it is not clear whether the application targeted must be in the form of a bundle or if the attacker can perform the attack against any privileged application with a custom bundle.
Users are advised to apply the patch provided by Apple, which changes the feature to prevent loading of plug-ins automatically if an executable is already loaded.
