Upgrade webkitgtk to version 2.48.7 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-Bounds due to improper memory handling. An attacker can cause a process crash or potentially execute arbitrary code by tricking a user into processing or loading malicious web content.
Note:
This is only exploitable if packages that require WebKitGTK4 (such as evolution-data-server, glade, gnome-boxes, gnome-initial-setup, gnome-online-accounts, gnome-shell, shotwell, sushi, or yelp) are installed and 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 removing the affected packages that require WebKitGTK4 or by avoiding the processing or loading of untrusted web content. WebKitGTK3 can also be removed without impacting system functionality.
