The manipulation leads to use after free. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. Upgrading to version 1.23.0 is able to address this issue. The identifier of the patch is 4bed614e707c0644c06e117f848fa12605c711cd. It is recommended to upgrade the affected component. In micropython objarray component, when a bytes object is resized and copied into itself, it may reference memory that has already been freed."

Durch Manipulation mit unbekannten Daten kann eine use after free-Schwachstelle ausgenutzt werden. Der Angriff kann \u00fcber das Netzwerk erfolgen. Die Komplexit\u00e4t eines Angriffs ist eher hoch. Sie gilt als schwierig ausnutzbar. Ein Aktualisieren auf die Version 1.23.0 vermag dieses Problem zu l\u00f6sen. Der Patch wird als 4bed614e707c0644c06e117f848fa12605c711cd bezeichnet. Als bestm\u00f6gliche Massnahme wird das Einspielen eines Upgrades empfohlen."
