CWE-416  (opens in a new tab)

How to fix?

Overview

Affected versions of this package are vulnerable to Use After Free in the process of handling web content. An attacker can cause a process crash or potentially execute arbitrary code by tricking a user into processing or loading specially crafted 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 avoiding the processing or loading of untrusted web content with the affected software, or by removing dependent packages that require the vulnerable component, though this may impact system functionality.
