"According to the versions of the gvfs packages installed, the EulerOS
installation on the remote host is affected by the following
vulnerabilities :

  - 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.(CVE-2019-12447)

  - An issue was discovered in GNOME gvfs 1.29.4 through
    1.41.2. daemon/gvfsbackendadmin.c has race conditions
    because the admin backend doesn't implement
    query_info_on_read/write.(CVE-2019-12448)

  - An issue was discovered in GNOME gvfs 1.29.4 through
    1.41.2. daemon/gvfsbackendadmin.c mishandles a file's
    user and group ownership during move (and copy with
    G_FILE_COPY_ALL_METADATA) operations from admin:// to
    file:// URIs, because root privileges are
    unavailable.(CVE-2019-12449)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
