Description
Slate Digital Connect 1.37.0 for macOS installs a privileged helper tool, com.slatedigital.connect.privileged.helper.tool, which exposes the XPC service com.slatedigital.connect.privileged.helper.tool2. The helper validates connecting XPC clients by obtaining the client's process identifier and using it to retrieve code-signing information for the process. This PID-based client validation is subject to a time-of-check time-of-use race condition because process identifiers can be reused. A local attacker can exploit PID reuse so that validation is performed against a trusted process instead of the original connecting process. This allows unauthorized access to privileged helper functionality and may lead to local privilege escalation.
