La vulnerabilit\u00e0 pi\u00f9 grave (CVE-2025-32023) potrebbe potenzialmente portare all'esecuzione di codice remoto sul server a causa della scrittura di dati in un'area al di fuori del buffer allocato. Per sfruttare la vulnerabilit\u00e0, l'attaccante deve essere in grado di inviare comandi al database.         <\/p>\n<p>Il problema \u00e8 causato da un errore nell'implementazione dei comandi che utilizzano l'algoritmo HyperLogLog per il conteggio approssimativo degli elementi unici in un insieme. Attraverso l'invio di una stringa appositamente formattata, l'attaccante pu\u00f2 innescare un overflow del buffer. La problematica colpisce tutte le versioni di Redis che supportano i comandi HLL. Come misura di protezione alternativa, si pu\u00f2 limitare l'accesso degli utenti ai comandi HLL tramite ACL.        <\/p>\n<p>La seconda vulnerabilit\u00e0 (CVE-2025-48367) pu\u00f2 essere sfruttata da un utente autenticato per provocare un'interruzione del servizio o una riduzione delle prestazioni del database.
