Overview

Affected versions of this package are vulnerable to Race Condition in the DRDYNVC parser when a channel pointer is dereferenced after releasing the synchronization lock. An attacker can execute arbitrary code or cause a denial of service by racing AUDIN channel closure messages against DRDYNVC data parsing to access freed channel objects.
