I g\u00e5r udgav Mozilla en patch til deres browser Firefox, som lukker en fejl med nul-dage. If\u00f8lge netkilder blev s\u00e5rbarheden aktivt udnyttet af kriminelle, men repr\u00e6sentanter fra Mozilla har endnu ikke kommenteret denne information.<\/p>\n

\"Mozilla<\/p>\n

Det er blevet oplyst, at s\u00e5rbarheden p\u00e5virkede JavaScript JIT-kompilatoren IonMonkey for SpiderMonkey, en af de centrale komponenter i Firefox-kernen, der h\u00e5ndterer JavaScript-operationer. Eksperter har klassificeret problemet som en type mismatch-s\u00e5rbarhed eller «type confusion», hvor information, der skrives til hukommelsen, f\u00f8rst defineres som en datatype, men senere skifter til en anden datatype p\u00e5 grund af bestemte manipulationer. Ved at udnytte denne s\u00e5rbarhed kunne angribere eksternt udf\u00f8re vilk\u00e5rlig kode p\u00e5 det angrebne system.      <\/p>\n

If\u00f8lge de oplysninger, der er tilg\u00e6ngelige, blev den p\u00e5g\u00e6ldende s\u00e5rbarhed opdaget af specialister fra det kinesiske firma Qihoo 360. Repr\u00e6sentanter for virksomheden sagde, at de er bekendt med en r\u00e6kke tilf\u00e6lde, hvor den n\u00e6vnte s\u00e5rbarhed blev udnyttet af kriminelle i praksis. Det skal n\u00e6vnes, at Qihoo 360 for nylig postede en meddelelse p\u00e5 Twitter om, at virksomheden havde opdaget en aktivt udnyttet nul-dages s\u00e5rbarhed i Internet Explorer-browseren. Denne meddelelse blev dog senere fjernet.<\/p>\n

Hvad ang\u00e5r den p\u00e5g\u00e6ldende s\u00e5rbarhed, s\u00e5 er den blevet rettet i versionerne 72.0.1 og Firefox ESR 68.4.1. Brugere af Mozillas browser anbefales at opdatere deres browser til den nyeste version for ikke at blive ofre for kriminelle.<\/p>\n
