A security vulnerability has been detected in LibreWolf up to 143.0.4-1 on Windows. This affects an unknown function of the file assets/setup.nsi of the component Installer. Such manipulation leads to uncontrolled search path. The attack must be carried out locally. Attacks of this nature are highly complex. The exploitability is reported as difficult. Upgrading to version 144.0-1 mitigates this issue. The name of the patch is dd10e31dd873e9cb309fad8aed921d45bf905a55. It is suggested to upgrade the affected component.
