CVE-2019-12447 [HIGH] GVfs vulnerabilities
Title: GVfs vulnerabilities
Summary: Several security issues were fixed in GVfs.
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)
Instructions: In general, a standard system update will make all the necessary changes.

gvfs: mishandling of file ownership in daemon/gvfsbackendadmin.c
An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles file ownership because setfsuid is not used.
It was discovered that gvfs incorrectly set the ownership of files handled by the admin:// backend. An attacker could abuse this flaw when the destination file of a copy/move operation is handled by the admin:// backend. The attacker would have access to the target files with the ability to read and write them.
