VAR-200412-0024

Vulnerability from variot - Updated: 2025-04-03 20:22

The CFPlugIn in Core Foundation framework in Mac OS X allows user supplied libraries to be loaded, which could allow local users to gain privileges. There is a vulnerability in the Apple QuickTime Streaming Server that could allow a remote attacker to cause a denial-of-service condition. 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. Mac OS X is an operating system used on Mac machines, based on the BSD system. Apple Mac OS X CoreFoundation has library loading processing issues and buffer overflows. Local attackers can exploit this vulnerability to obtain ROOT privileges. Apple reports that local users can use the CoreFoundation CFPlugIn application to load any user-provided library to obtain ROOT privileges [CVE: CAN -2004-0821]. In addition, local users can modify some environment variables to trigger buffer overflow in CoreFoundation, and can execute arbitrary commands with ROOT process privileges [CVE: CAN-2004-0822]
