Overview
Affected versions of this package are vulnerable to Use After Free in the control process. An attacker can cause memory corruption and potentially crash the process by connecting to the control socket and sending a privileged command, which leads to freeing a client object while a subsequent event accesses a stale pointer. This is only exploitable if privilege separation is disabled or if privilege separation initialization has failed and the control socket operates in mode 0666.
