CVE-2020-16123 is fixed in 14 products on 1 platform, first by libpulse-mainloop-glib0 1:11.1-1ubuntu7.11, released November 23, 2020. It is not reported as exploited. Patch Radar priority: Routine.
An Ubuntu-specific patch in PulseAudio created a race condition where the snap policy module would fail to identify a client connection from a snap as coming from a snap if SCM_CREDENTIALS were missing, allowing the snap to connect to PulseAudio without proper confinement. This could be exploited by an attacker to expose sensitive information. Fixed in 1:13.99.3-1ubuntu2, 1:13.99.2-1ubuntu2.1, 1:13.99.1-1ubuntu3.8, 1:11.1-1ubuntu7.11, and 1:8.0-0ubuntu3.15.
