In de CPython-klassen voor het uitpakken van gecomprimeerde gegevens in de formaten lzma, bz2 en gzip (lzma.LZMADecompressor, bz2.BZ2Decompressor en gzip.GzipFile) is een kwetsbaarheid vastgesteld (CVE-2026-6100) die leidt tot toegang tot geheugen na vrijgave. Het probleem heeft een kritieke gevaarlijkheidsgraad gekregen (9.1 van 10) \u2014 bij succesvolle exploitatie kan de kwetsbaarheid leiden tot informatielekkage uit het geheugen van het proces of de uitvoering van de code van de aanvaller bij het uitpakken van speciaal ontworpen gegevens. Een oplossing is momenteel beschikbaar in de vorm van een patch. <\/p>\n

Het probleem doet zich voor na het be\u00ebindigen van de geheugenallocatie door een fout die optreedt bij een gebrek aan geheugen (voor succesvolle exploitatie van de kwetsbaarheid moet de aanvaller voorwaarden cre\u00ebren voor het uitputten van het beschikbare procesgeheugen). Toegang tot al vrijgegeven geheugen komt voor in applicaties die een objectexemplaar hergebruiken na het terugkeren van een fout tijdens het uitpakken. Applicaties die bij elke aanroep een nieuw objectexemplaar aanmaken, zijn niet kwetsbaar.
