I de levererade klasserna f\u00f6r avpackning av komprimerade data i formaten lzma, bz2 och gzip (lzma.LZMADecompressor, bz2.BZ2Decompressor och gzip.GzipFile) har en s\u00e5rbarhet identifierats (CVE-2026-6100) som leder till \u00e5tkomst till minne efter att det har frigjorts. Problemet har tilldelats en kritisk riskniv\u00e5 (9.1 av 10) \u2014 om s\u00e5rbarheten utnyttjas framg\u00e5ngsrikt kan den leda till l\u00e4ckage av information fr\u00e5n processens minne eller exekvering av angriparens kod vid avpackning av specialdesignade data. En l\u00f6sning finns f\u00f6r n\u00e4rvarande tillg\u00e4nglig i form av en patch. <\/p>\n

Problemet visar sig efter att minnesallokerings operationen avslutas med ett fel som uppst\u00e5r vid minnesbrist (f\u00f6r att ett angrepp skall lyckas, m\u00e5ste angriparen skapa villkor som utt\u00f6mmer den tillg\u00e4ngliga processen av minne). \u00c5tkomst till redan frigjort minne uppst\u00e5r i applikationer som \u00e5teranv\u00e4nder objektinstansen efter att felet har \u00e5terl\u00e4mnats under avpackning.
