Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS : GNOME Shell vulnerability (USN-6963-1)

medium Nessus Plugin ID 205629

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6963-1 advisory.

It was discovered that GNOME Shell incorrectly opened the portal helper automatically when detecting a captive network portal. A remote attacker could possibly use this issue to load arbitrary web pages containing JavaScript, leading to resource consumption or other attacks.

Tenable has extracted the preceding description block directly from the Ubuntu 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

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