SpeechD Privileged Command Execution Vulnerability

SpeechD is a device-independent layer for speech synthesis under Linux, providing an interface for speech-based applications or device drivers.

SpeechD has been found to contain a flaw under certain implementations which can permit a local user to pass malcious commands to the /dev/speech device, and have them executed with the privilege level of the speechd user, which is usually root.
