Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the gdm3 packages.

For the stable distribution (stretch), this problem has been fixed in version 3.22.3-3+deb9u2.
