Updates voor versie 9.6 worden tot november 2021 gemaakt, 10 \u2014 tot november 2022, 11 \u2014 tot november 2023, 12 \u2014 tot november 2024 en 13 tot november 2025. In de nieuwe releases zijn drie kwetsbaarheden verholpen en zijn opgelopen fouten gecorrigeerd.    <\/p>\n<p> Kwetsbaarheid CVE-2021-32027 kan leiden tot het schrijven van gegevens buiten de buffer door een integer overflow tijdens het berekenen van array-indexen. Door manipulatie met array-waarden in SQL-query's kan een aanvaller met toegang tot het uitvoeren van SQL-query's willekeurige gegevens in een willekeurig geheugenadres van het proces schrijven en zijn code met de juiste rechten uitvoeren. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/nl\/server\/dts-los-angeles\/\"   title=\"de server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3715\">de server<\/a> DBMS. Twee andere kwetsbaarheden (CVE-2021-32028, CVE-2021-32029) leiden tot een lek van de inhoud van het geheugenproces bij manipulatie met de queries \u2018INSERT ... ON CONFLICT ... DO UPDATE\u2019 en \u2018UPDATE ... RETURNING\u2019.    <\/p>\n<p>Wat niet-kwetsbaarheidsgerelateerde correcties betreft, kunnen de volgende worden opgemerkt:  <\/p>\n<ul>\n<li class=\"l\"> Verwerking van incorrecte berekeningen bij het uitvoeren van \u2018UPDATE ... RETURNING\u2019 voor het bijwerken van samengevoegde segmentatietabellen.\n<li class=\"l\"> Verhelpen van de fout van de opdracht \u2018ALTER TABLE ... ALTER CONSTRAINT\u2019 bij aanwezigheid van beperkingen voor externe sleutels in combinatie met het gebruik van segmentatietabellen.\n<li class=\"l\"> De functionaliteit \u2018COMMIT AND CHAIN\u2019 werkt nu correct.\n<li class=\"l\"> Voor nieuwe releases van FreeBSD is de modus fdatasync als standaard ingesteld in thatwal_sync_method.\n<li class=\"l\"> De parameter vacuum_cleanup_index_scale_factor is standaard uitgeschakeld.\n<li class=\"l\"> Geheugenlekken die zich voordoen bij de initialisatie van TLS-verbindingen zijn verholpen.\n<li class=\"l\"> In pg_upgrade zijn aanvullende controles toegevoegd om te controleren op het bestaan van datatypes in gebruikers tabellen die niet kunnen worden ge\u00fcpdatet.  <\/ul>\n<p>Bron: <a content=\"nofollow\"
