Publiceret<\/a><\/noindex> Korrigerende opdateringer til stabile versioner af DNS-serveren BIND 9.14.3, 9.11.8 og 9.12.4-P2 samt den eksperimentelle version 9.15.1, der er under udvikling. Samtidig er der blevet annonceret, at der ikke l\u00e6ngere vil v\u00e6re st\u00f8tte til version 9.12, og der vil ikke blive udgivet flere opdateringer til denne version. <\/p>\n

Opdateringerne er bem\u00e6rkelsesv\u00e6rdige for at fjerne s\u00e5rbarheder<\/a><\/noindex> (CVE-2019-6471<\/a><\/noindex>), som muligg\u00f8r en nedbrud af tjenesten (processen afsluttes med assertion REQUIRE). Problemet skyldes en race condition, der opst\u00e5r ved behandling af et meget stort antal specielt udformede indg\u00e5ende pakker, der falder ind under blokkeringsfilteret. For at udnytte s\u00e5rbarheden skal angriberen sende et stort antal foresp\u00f8rgsler til offerets resolver, som f\u00f8rer til anmodninger til angriberens DNS-server, der returnerer ukorrekte svar.<\/p>\n
