USN-4355-1: PulseAudio vulnerability
First published: Tue May 12 2020(Updated: )
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.
