Executive Summary

This vulnerability is a local privilege escalation issue in the Plugin Alliance InstallationHelper service on macOS. Because the service lacks a hardened runtime and a __RESTRICT segment, a local user can exploit the DYLD_INSERT_LIBRARIES environment variable to inject a dynamic library. This allows the user to execute code with elevated privileges.

Impact Analysis

The vulnerability can allow a local user to gain elevated privileges on the affected system by injecting malicious code into the InstallationHelper service. This could lead to unauthorized actions being performed with higher privileges than intended, potentially compromising system security.
