Mozilla har udgivet nye versioner af webbrowserne Firefox 74.0.1 og Firefox ESR 68.6.1. Brugere opfordres til at opdatere deres browsere, da der i de pr\u00e6senterede versioner er rettet to null-dages s\u00e5rbarheder, som hackere udnytter i praksis.<\/p>\n

\"To<\/p>\n

Det drejer sig om s\u00e5rbarhederne CVE-2020-6819 og CVE-2020-6820, som er relateret til, hvordan Firefox h\u00e5ndterer sit hukommelsesrum. De udg\u00f8r s\u00e5kaldte s\u00e5rbarheder for brug af hukommelse efter frigivelse og giver hackere mulighed for at inds\u00e6tte vilk\u00e5rlig kode i Firefox' hukommelse til efterf\u00f8lgende udf\u00f8relse i browserens kontekst. Disse s\u00e5rbarheder kan bruges til at udf\u00f8re kode eksternt p\u00e5 offerets enheder.<\/p>\n

Detaljer om reelle angreb, der udnytter de n\u00e6vnte s\u00e5rbarheder, afsl\u00f8res ikke, hvilket er almindelig praksis blandt softwareleverand\u00f8rer og forskere inden for informationssikkerhed. Dette skyldes, at de alle normalt fokuserer p\u00e5 hurtigt at l\u00f8se de opdagede problemer og levere rettelser til brugerne, hvorefter en mere detaljeret unders\u00f8gelse af angrebene gennemf\u00f8res.<\/p>\n

If\u00f8lge tilg\u00e6ngelige oplysninger vil Mozilla efterforske angrebene, der bruger disse s\u00e5rbarheder, i samarbejde med sikkerhedsfirmaet JMP Security og forskeren Francisco Alonso, der f\u00f8rst opdagede problemet. Forskeren antyder, at de s\u00e5rbarheder, der er blevet rettet i den seneste Firefox-opdatering, muligvis ogs\u00e5 p\u00e5virker andre browsere, selvom der ikke er rapporteret om tilf\u00e6lde, hvor fejlene er blevet udnyttet af hackere i forskellige webbrowsere.<\/p>\n
