SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt 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.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected gnome-shell package.
