I problemi sono stati risolti finora solo sotto forma di patch (CVE-2021-21898, CVE-2021-21899, CVE-2021-21900).\n<li class=\"l\"> Vulnerabilit\u00e0 (CVE-2021-41817) nel metodo Date.parse fornito dalla libreria standard del linguaggio Ruby. Le mancanze nelle espressioni regolari utilizzate per l'analisi delle date nel metodo Date.parse possono essere sfruttate per attacchi DoS, causando un significativo consumo di risorse CPU e memoria durante l'elaborazione di dati appositamente formattati.\n<li class=\"l\"> Una vulnerabilit\u00e0 nella piattaforma di machine learning TensorFlow (CVE-2021-41228) consente l'esecuzione di codice arbitrario durante l'elaborazione dei dati dell'attaccante tramite lo strumento saved_model_cli, attraverso il parametro &#171;&#8212;input_examples&#187;.

Questo problema consente l'esecuzione di codice JavaScript tramite l'indicazione di un URL appositamente formattato nella pagina delle impostazioni. In Mailman \u00e8 stata identificata anche un'altra vulnerabilit\u00e0 (CVE-2021-43332), che consente a un utente con privilegi di moderazione di trovare la password dell'amministratore.
