Details

It was discovered that GVfs incorrectly handled the admin backend. Files
created or moved by the admin backend could end up with the wrong ownership
information, contrary to expectations. This issue only affected Ubuntu
18.04 LTS, Ubuntu 18.10, and Ubuntu 19.04. (CVE-2019-12447, CVE-2019-12448,
CVE-2019-12449)

It was discovered that GVfs incorrectly handled authentication on its
private D-Bus socket. A local attacker could possibly connect to this
socket and issue D-Bus calls. (CVE-2019-12795)
