Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 20.04 LTS - Ubuntu 19.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS Summary: PulseAudio could allow unintended access to snap packages. Software Description: - pulseaudio: PulseAudio sound server Details: PulseAudio in Ubuntu contains additional functionality to mediate audio recording for snap packages and it was discovered that this functionality did not mediate PulseAudio module unloading. An attacker-controlled snap with only the audio-playback interface connected could exploit this to bypass access controls and record audio. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: Ubuntu 19.10: Ubuntu 18.04 LTS: Ubuntu 16.04 LTS: After a standard system update you need to restart your session to make all the necessary changes.
