Title: SpeechD Privileged Command Execution Vulnerability
Severity: MODERATE
Description:
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 an input validation flaw under certain implementations. User input is accepted and passed to a system() call without having been checked for shell metacharacters. This can permit a local user to pass arbitrary commands to be executed at the privilege level of speechd by passing them to the /dev/speech device.
This issue has been confirmed to affect speechd running with the rsynth application. It may also potentially affect festival and other applications.
Affected Products:
- SpeechIO SpeechD 0.1.0
- SpeechIO SpeechD 0.2.0
