\n(«orphaned»), \u0161to implicira prekid njegovog testiranja.<\/p>\n

Voza\u010d se smatra zastarjelim, jer je te\u0161ko prona\u0107i radnu opremu za njegovo testiranje \u2014 svi aktualni vanjski ure\u0111aji obi\u010dno koriste USB su\u010delje.

Stoga se voza\u010d za sada zadr\u017eava u jezgri, ali njegova ispravna funkcionalnost nije zajam\u010dena.<\/p>\n

Osim toga, u upravlja\u010du floppy rije\u0161ena<\/a><\/noindex> ranljivost<\/a><\/noindex> (CVE-2019-14283<\/a><\/noindex>), omogu\u0107avaju\u0107i neprivilegiranom korisniku, koji ima mogu\u0107nost umetanja vlastitog floppy diska, da pro\u010dita podatke iz memorijskih podru\u010dja izvan granica kopirnog bafera (na primjer, u susjednim podru\u010djima mogu se nalaziti preostali podaci iz diska ke\u0161a i ulaznog bafera). S jedne strane, ranjivost ostaje aktualna jer se floppy upravlja\u010d automatski u\u010ditava u prisutnosti odgovaraju\u0107eg emuliranog kontrolera u virtualizacijskim sustavima (na primjer, prema zadanim postavkama koristi se u QEMU), ali s druge strane, za iskori\u0161tavanje problema potrebno je imati pripremljenu sliku floppy diska koju je spojio napada\u010d.<\/p>\n
