Affected versions of this package are vulnerable to Buffer Overflow.
in the memory process. An attacker can execute arbitrary code or compromise system integrity by tricking a user into visiting a maliciously crafted web page. This is only exploitable if the system is configured with packages that require WebKitGTK4 (such as evolution-data-server, glade, gnome-boxes, gnome-initial-setup, gnome-online-accounts, gnome-shell, shotwell, sushi, or yelp) and these are used via a graphical interface to process untrusted web content, for example through GNOME. In gnome-shell, exploitation can occur from the local network without user interaction.
Workaround
This vulnerability can be mitigated by not visiting untrusted web pages or loading untrusted web content with WebKitGTK, or by removing packages that require WebKitGTK4 or WebKitGTK3 as appropriate.
