Ubuntu 16.04 LTS : GNOME Shell vulnerabilities (USN-7052-1)

high Nessus Plugin ID 208068

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7052-1 advisory.

 It was discovered that GNOME Shell mishandled extensions that fail to reload, possibly leading to extensions staying enabled on the lock screen. An attacker could possibly use this issue to launch applications, view

 sensitive information, or execute arbitrary commands. (CVE-2017-8288)

 It was discovered that the GNOME Shell incorrectly handled certain keyboard inputs. An attacker could possibly use this issue to invoke keyboard shortcuts, and potentially other actions while the workstation was locked. (CVE-2019-3820)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected gnome-shell and / or gnome-shell-common packages.
