Kod programskog paketa Adobe Flash Player uočeno je više sigurnosnih nedostataka. Napadač ih može iskoristiti za dobivanje većih privilegija, zaobilaženje postavljenih ograničenja, napad uskraćivanjem usluga (DoS), otkrivanje podataka te izvršavanje proizvoljnog programskog koda.
Sigurnosni propusti se javljaju zbog neodgovarajućeg rukovanja ulaznim podacima, višestrukih preljeva međuspremnika, cjelobrojnog prepisivanja, itd.
Posljedica:
Zloćudni korisnik navedene propuste može iskoristiti za DoS (eng. Denial of Service) napad, proizvoljno pokretanje programskog koda, otkrivanje osjetljivih informacija, dobivanje većih ovlasti te zaobilaženje postavljenih ograničenja.
Rješenje:
Problem se ispravlja nadogradnjom sustava s izdanim ažuriranim paketima.
