Overview
Affected versions of this package are vulnerable to Use After Free via the process of handling maliciously crafted web content. An attacker can execute arbitrary code or cause a process crash by tricking a user into processing or loading malicious web content. This is only exploitable if the system has specific packages installed and is being used via a graphical interface to process untrusted web content, such as through GNOME.
Workaround
This vulnerability can be mitigated by removing the affected packages that require WebKitGTK4 or WebKitGTK3, though this may impact system functionality, especially if GNOME is in use.
