Package : gdm3
CVE ID : CVE-2018-14424
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.
