USN-4519-1

Ratchanan Srirattanamet discovered that an Ubuntu-specific patch caused PulseAudio to incorrectly handle memory under certain error conditions in the Bluez 5 module. An attacker could use this issue to cause PulseAudio to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-15710)
