CriticalCVSS 9.3
Published: Translated: NVD NIST

Summary

In the RingRTC library before 2.72.0 for Signal, a peer that saturates a call's FSM queue can interfere with the ability of a local hangup to tear the call (with its audio and perhaps also video track) down.

Risk Assessment

An attacker can prevent a user from ending a call, potentially leaving an active audio/video stream unexpectedly and causing privacy concerns.

Recommendation

Update the RingRTC library to version 2.72.0 or later in applications using Signal.
