U radu programskog paketa nginx uočena su i ispravljena dva nedostatka. Zlonamjerni napadači su ih mogli iskoristiti za otkrivanje osjetljivih informacija, proizvoljno izvođenje programskog koda i DoS napad.
Propusti su posljedica preljeva međuspremnika u programskoj komponenti "ngx_http_mp4_module.c" i neodgovarajućeg rukovanja slobodnom memorijom.
Posljedica:
Navedene ranjivosti udaljeni napadači mogu iskoristiti za prepisivanje proizvoljnih memorijskih lokacija, proizvoljno izvođenje programskog koda i napad uskraćivanjem usluga (DoS).
Rješenje:
Kao rješenje problema sigurnosti savjetuje se primjena službenih programskih zakrpi.
