Descriptions

An event handler validation issue in the XPC Services API was addressed by removing the service. This issue is fixed in macOS Monterey 12.2. An application may be able to delete files for which it does not have permission.

Se abordó un problema de comprobación de manejadores de eventos en la API de servicios XPC mediante la eliminación del servicio. Este problema es corregido en macOS Monterey versión 12.2. Una aplicación puede ser capaz de eliminar archivos para los que no presenta permiso

This vulnerability allows local attackers to bypass System Integrity Protection on affected installations of Apple macOS. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within PackageKit. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to escalate privileges and delete files normally protected from the user.
