Overview
Affected versions of this package are vulnerable to Improper Control of a Resource Through its Lifetime in the state management process. An attacker can cause an application to become unresponsive or crash by tricking a user into visiting a specially crafted malicious website. This is only exploitable if the affected packages are installed and used via a graphical interface to process untrusted web content, such as through GNOME. In some cases, exploitation may occur from the local network without user interaction.
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 or related packages are in use.
