21631 Advisory: ======================== Updated gnome-shell packages fix security vulnerability: 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). A use-after-free flaw was found in the way gnome-shell handled mapping and unmapping of tray icons. A malicious or misbehaving local application could potentially use this flaw to crash the gnome-shell process (rhbz#1492007). The gnome-shell package has been updated to 3.24.3 and patched to fix these issues and other bugs.
