Amazon Linux 2 : gnome-shell (ALAS-2020-1478)

medium Nessus Plugin ID 139855

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of gnome-shell installed on the remote host is prior to 3.28.3-24. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1478 advisory.

It was discovered that the gnome-shell lock screen since version 3.15.91 did not properly restrict all contextual actions. An attacker with physical access to a locked workstation could invoke certain keyboard shortcuts, and potentially other actions. (CVE-2019-3820)

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

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

Solution

Run 'yum update gnome-shell' to update your system.
