Es betrifft die Funktion ndlz8_decompress der Datei /src/c-blosc2/plugins/codecs/ndlz/ndlz8x8.c. Dank der Manipulation mit unbekannten Daten kann eine heap-based buffer overflow-Schwachstelle ausgenutzt werden. Der Angriff kann \u00fcber das Netzwerk erfolgen. Der Exploit steht zur \u00f6ffentlichen Verf\u00fcgung. Ein Aktualisieren auf die Version 2.14.3 vermag dieses Problem zu l\u00f6sen. Als bestm\u00f6gliche Massnahme wird das Einspielen eines Upgrades empfohlen."
