Utvecklarna p\u00e5 Mozilla har sl\u00e4ppt nya versioner av webbl\u00e4sarna Firefox 74.0.1 och Firefox ESR 68.6.1. Anv\u00e4ndarna rekommenderas att uppdatera sina webbl\u00e4sare eftersom de nya versionerna \u00e5tg\u00e4rdar tv\u00e5 noll-dagars s\u00e5rbarheter som utnyttjas av hackare i praktiken.<\/p>\n

\"Tv\u00e5<\/p>\n

Det handlar om s\u00e5rbarheterna CVE-2020-6819 och CVE-2020-6820, som r\u00f6r hur Firefox hanterar sitt minnesutrymme. Dessa utg\u00f6r s\u00e5 kallade s\u00e5rbarheter f\u00f6r anv\u00e4ndning av minnet efter frig\u00f6ring och till\u00e5ter hackare att placera godtycklig kod i Firefoxs minne f\u00f6r vidare exekvering i webbl\u00e4sarens kontext. S\u00e5dana s\u00e5rbarheter kan anv\u00e4ndas f\u00f6r fj\u00e4rr exekvering av kod p\u00e5 offrets enheter.<\/p>\n

Detaljerad information om verkliga attacker som utnyttjar de n\u00e4mnda s\u00e5rbarheterna avsl\u00f6jas inte, vilket \u00e4r en vanlig praxis bland programvaruleverant\u00f6rer och forskare inom informationss\u00e4kerhet. Detta beror p\u00e5 att de normalt fokuserar p\u00e5 att omg\u00e5ende \u00e5tg\u00e4rda uppt\u00e4ckta problem och leverera l\u00f6sningar till anv\u00e4ndarna, och f\u00f6rst efter det genomf\u00f6rs en mer detaljerad utredning av attackerna.<\/p>\n

Enligt tillg\u00e4ngliga uppgifter kommer Mozilla att utreda attacker som utnyttjar dessa s\u00e5rbarheter i samarbete med s\u00e4kerhetsf\u00f6retaget JMP Security och forskaren Francisco Alonso, som var den f\u00f6rsta som uppt\u00e4ckte problemet. Forskaren antyder att de s\u00e5rbarheter som \u00e5tg\u00e4rdades i den senaste Firefox-uppdateringen kan p\u00e5verka andra webbl\u00e4sare, \u00e4ven om det inte finns n\u00e5gra k\u00e4nda fall d\u00e4r felen utnyttjats av hackare i olika webbl\u00e4sare.<\/p>\n
