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.");
