Updated gnome-shell packages fix security vulnerability

Publication date: 03 Jan 2018
Type: security
Affected Mageia releases : 5
CVE: CVE-2017-8288


gnome-shell through 3.24.1 mishandles extensions that fail to reload,
which can lead to leaving extensions enabled in the lock screen. With
these extensions, a bystander could launch applications (but not interact
with them), see information from the extensions (e.g., what applications
you have opened or what music you were playing), or even execute arbitrary
commands. It all depends on what extensions a user has enabled. The
problem is caused by lack of exception handling in
js/ui/extensionSystem.js (CVE-2017-8288).
