    Chris Coulson discovered a use-after-free flaw in the GNOME Display
    Manager, triggerable by an unprivileged user via a specially crafted
    sequence of D-Bus method calls, leading to denial of service or
    potentially the execution of arbitrary code.
    
    For the stable distribution (stretch), this problem has been fixed in
    version 3.22.3-3+deb9u2.
    
    We recommend that you upgrade your gdm3 packages.

    tracker page at:
