Nei moduli di decompressione inclusi in CPython per i formati di dati compressi lzma, bz2 e gzip (lzma.LZMADecompressor, bz2.BZ2Decompressor e gzip.GzipFile) \u00e8 stata identificata una vulnerabilit\u00e0 (CVE-2026-6100), che porta a un accesso alla memoria dopo che \u00e8 stata liberata. Il problema ha ricevuto un livello critico di gravit\u00e0 (9.1 su 10) \u2014 se sfruttata con successo, la vulnerabilit\u00e0 pu\u00f2 causare una fuoriuscita di informazioni dalla memoria del processo o l'esecuzione di codice da parte dell'attaccante durante la decompressione di dati appositamente formattati. Una correzione \u00e8 al momento disponibile in forma di patch. <\/p>\n

Il problema si manifesta dopo il termine dell'operazione di allocazione della memoria a causa di un errore che si verifica in caso di esaurimento della memoria (per un riuscito sfruttamento della vulnerabilit\u00e0, l'attaccante deve creare condizioni di esaurimento della memoria disponibile per il processo). L'accesso alla memoria gi\u00e0 liberata si verifica nelle applicazioni che riutilizzano un'istanza dell'oggetto dopo che si \u00e8 verificato un errore durante la decompressione. Le applicazioni che creano una nuova istanza dell'oggetto a ogni chiamata non sono vulnerabili.
